* py/objfloat: Raise ZeroDivisionError for 0 to negative power.Damien George2017-02-03
|
* py: Use mp_raise_msg helper function where appropriate.Damien George2016-10-17
| | | | | Saves the following number of bytes of code space: 176 for bare-arm, 352 for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.
* py/objfloat, py/modmath: Ensure M_PI and M_E defined.Colin Hogben2016-05-12
| | | | | | In some compliation enviroments (e.g. mbed online compiler) with strict standards compliance, <math.h> does not define constants such as M_PI. Provide fallback definitions of M_E and M_PI where needed.
* py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George2016-01-11
| | | | | | | | The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.
* py: Change type of .make_new and .call args: mp_uint_t becomes size_t.Damien George2016-01-11
| | | | | | | This patch changes the type signature of .make_new and .call object method slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more efficient when mp_uint_t is larger than a machine word. Doesn't affect ports when size_t and mp_uint_t have the same size.
* py: Add support for 64-bit NaN-boxing object model, on 32-bit machine.Damien George2015-11-29
| | | | | | | | | | | | | To use, put the following in mpconfigport.h: #define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D) #define MICROPY_FLOAT_IMPL (MICROPY_FLOAT_IMPL_DOUBLE) typedef int64_t mp_int_t; typedef uint64_t mp_uint_t; #define UINT_FMT "%llu" #define INT_FMT "%lld" Currently does not work with native emitter enabled.
* py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.Damien George2015-11-29
| | | | | | | | | This allows the mp_obj_t type to be configured to something other than a pointer-sized primitive type. This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts.
* py: Add object repr "C", where 30-bit floats are stuffed in obj word.Damien George2015-10-20
| | | | | | This new object representation puts floats into the object word instead of on the heap, at the expense of reducing their precision to 30 bits. It only makes sense when the word size is 32-bits.
* py: Make float representation configurable with object representation.Damien George2015-10-20
|
* py: Move float e/pi consts to objfloat and make mp_obj_float_t private.Damien George2015-10-20
|
* py: Add mp_obj_is_float function (macro) and use it where appropriate.Damien George2015-10-20
|
* py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky2015-10-11
|
* py: Add MP_BINARY_OP_DIVMOD to simplify and consolidate divmod builtin.Damien George2015-06-13
|
* py: Implement mp_format_float for doubles and use where appropriatestijn2015-05-17
| | | | | | | This allows using (almost) the same code for printing floats everywhere, removes the dependency on sprintf and uses just snprintf and applies an msvc-specific fix for snprintf in a single place so nan/inf are now printed correctly.
* py: Fix printing of "inf" and "nan" floating point values.Damien George2015-04-22
|
* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
* py, extmod: Remove include of unnecessary system headers.Damien George2015-03-14

* py: Parse big-int/float/imag constants directly in parser.Damien George2015-02-08
| | | | | | | | | Previous to this patch, a big-int, float or imag constant was interned (made into a qstr) and then parsed at runtime to create an object each time it was needed. This is wasteful in RAM and not efficient. Now, these constants are parsed straight away in the parser and turned into objects. This allows constants with large numbers of digits (so addresses issue #1103) and takes us a step closer to #722.
* py, unix: Allow to compile with -Wunused-parameter.Damien George2015-01-20
| | | | See issue #699.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py: Implement divmod, % and proper // for floating point.Damien George2014-09-13
| | | | Tested and working on unix and pyboard.
* py and libm: Add asinf,acosf; print higher precision for float.Damien George2014-09-11
| | | | | | Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851.
* py: Change all uint to mp_uint_t in obj.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George2014-08-30
| | | | Addressing issue #50, still some way to go yet.
* py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT.Paul Sokolovsky2014-06-20
| | | | | One thing is wanting to do 1 / 2 and get something else but 0, and quite another - doing rocket science ;-).
* Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George2014-06-01
| | | | | | | | | | This renames: MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT See issue #35 for discussion.
* py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George2014-05-21
| | | | See issue #608 for justification.
* py: Use mp_arg_check_num in more places.Damien George2014-05-11
| | | | | | | | | Updated functions now do proper checking that n_kw==0, and are simpler because they don't have to explicitly raise an exception. Down side is that the error messages no longer include the function name, but that's acceptable. Saves order 300 text bytes on x64 and ARM.
* py: Tidy up returning NULL which should be MP_OBJ_NOT_SUPPORTED.Damien George2014-05-10
|
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
* py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky2014-05-02
| | | | Specifically, nlr.h does.
* objfloat: Try to achieve the same float printing format as CPython does.Paul Sokolovsky2014-04-18
| | | | | | | Test usecase I used is print(time.time()) and print(time.time() - time.time()). On Linux/Glibc they now give the same output as CPython 3.3. Specifically, time.time() gives non-exponential output with 7 decimal digits, and subtraction gives exponential output e-06/e-07.
* py: Add MP_OBJ_STOP_ITERATION and make good use of it.Damien George2014-04-17
| | | | | Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL. This helps a lot in debugging and understanding of function API.

* py: Change nlr_jump to nlr_raise, to aid in debugging.Damien George2014-04-05

* objfloat: Quick&dirty implementation of float floor division.Paul Sokolovsky2014-03-31
| | | | TODO: Likely doesn't match Python semantics for negative numbers.
* objfloat: Make sure that floats always have dot (for C "double" type case).Paul Sokolovsky2014-03-31
| | | | | This matches CPython behavior and hopefully can be treated as general Python semantics.
* objfloat: Missing default: caused incorrect results for unimplemented ops.Paul Sokolovsky2014-03-31
|
* Rename rt_* to mp_*.Damien George2014-03-30
| | | | | | | Mostly just a global search and replace. Except rt_is_true which becomes mp_obj_is_true. Still would like to tidy up some of the names, but this will do for now.
