From 5cbeacebdb8407425e692205f7333452e8a57784 Mon Sep 17 00:00:00 2001 From: Damien George Date: Sun, 22 Feb 2015 14:48:18 +0000 Subject: py: Make math special functions configurable and disabled by default. The implementation of these functions is very large (order 4k) and they are rarely used, so we don't enable them by default. They are however enabled in stmhal and unix, since we have the room. --- py/modmath.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'py/modmath.c') diff --git a/py/modmath.c b/py/modmath.c index 38ed390ddf..46423d2b5c 100644 --- a/py/modmath.c +++ b/py/modmath.c @@ -120,6 +120,7 @@ MATH_FUN_1_TO_BOOL(isnan, isnan) MATH_FUN_1_TO_INT(trunc, trunc) /// \function ldexp(x, exp) MATH_FUN_2(ldexp, ldexp) +#if MICROPY_PY_MATH_SPECIAL_FUNCTIONS /// \function erf(x) /// Return the error function of `x`.
