From 4caa17b2a17d136efedfb63fceef832401063d70 Mon Sep 17 00:00:00 2001 From: nsz Date: Mon, 19 Mar 2012 23:30:45 +0100 Subject: don't try to create non-standard denormalization signal Underflow exception is only raised when the result is invalid, but fmod is always exact. x87 has a denormalization exception, but that's nonstandard. And the superflous *1.0 will be optimized away by any compiler that does not honor signaling nans. --- src/math/fmodf.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/math/fmodf.c') diff --git a/src/math/fmodf.c b/src/math/fmodf.c index 4b50a3d3..837e9371 100644 --- a/src/math/fmodf.c +++ b/src/math/fmodf.c @@ -20,7 +20,7 @@ #include "libm.h" -static const float one = 1.0, Zero[] = {0.0, -0.0,}; +static const float Zero[] = {0.0, -0.0,}; float fmodf(float x, float y) { @@ -99,7 +99,6 @@ float fmodf(float x, float y) n = -126 - iy; hx >>= n; SET_FLOAT_WORD(x, hx|sx); - x *= one; /* create necessary signal */ } return x; /* exact output */ } -- cgit v1.2.1
