* py: Implement raising a big-int to a negative power.Damien George2017-07-25
| | | | | Before this patch raising a big-int to a negative power would just return 0. Now it returns a floating-point number with the correct value.
* py/modmath: Check for zero division in log with 2 args.Damien George2017-07-04
|
* py/formatfloat: Fix number of digits and exponent sign when rounding.Damien George2017-06-13
| | | | | | | This patch fixes 2 things when printing a floating-point number that requires rounding up of the mantissa: - retain the correct precision; eg 0.99 becomes 1.0, not 1.00 - if the exponent goes from -1 to 0 then render it as +0, not -0
* tests/float/builtin_float_minmax: PEP8 fixes.Paul Sokolovsky2017-06-08
|
* tests/float: Convert "sys.exit()" to "raise SystemExit".Damien George2017-06-08
| | | | | The latter is shorter and simpler because it doesn't require importing the sys module.
* tests/float: Add tests for hashing float and complex numbers.Damien George2017-04-04
|
* tests/float/byte*_construct: Skip on missing array module.Paul Sokolovsky2017-04-03
|
* tests/float: Add tests for round() of inf, nan and large number.Damien George2017-03-24
|
* tests/float: Add tests for math funcs that return ints.Damien George2017-03-23
| | | | One should test bigint, inf and nan to make sure all cases are covered.
* tests/float: Make various tests skippable.Paul Sokolovsky2017-03-09
|
* tests/string_format_modulo2: Split off intbig test.Paul Sokolovsky2017-03-07
|
* tests/float2int*: Suffix with _intbig, don't run on any other int type.Paul Sokolovsky2017-03-06
| | | | | | I.e. they don't run successfully with MICROPY_LONGINT_IMPL_NONE and MICROPY_LONGINT_IMPL_LONGLONG (the problem is that they generate different output than CPython, TODO to fix that).
* float/float2int*: Make actually be parsable for MICROPY_LONGINT_IMPL_NONE.Paul Sokolovsky2017-03-06
| | | | | | | | | | | | The use of large literal numbers is a big no-no when it comes to writing programs which work with different int representations. Also, some checks are pretty adhoc (e.g using struct module to check for 64-bitness). This change bases entire detection on sys.maxsize and integer operarions, and thus more correct, even if longer. Note that this change doesn't mean that any of these tests can pass with anything but MPZ - even despite checking for various int representations, the tests aren't written to be portable among them.

* tests: Add some tests for printing floats to improve coverage.Damien George2015-05-28
|
* py: Remove unnecessary extra handling of padding of nan/inf.Damien George2015-05-28
| | | | | | | C's printf will pad nan/inf differently to CPython. Our implementation originally conformed to C, now it conforms to CPython's way. Tests for this are also added in this patch.
* 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.
