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/fmod.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/math/fmod.c') diff --git a/src/math/fmod.c b/src/math/fmod.c index 6856844e..84a1b4ac 100644 --- a/src/math/fmod.c +++ b/src/math/fmod.c @@ -17,7 +17,7 @@ #include "libm.h" -static const double one = 1.0, Zero[] = {0.0, -0.0,}; +static const double Zero[] = {0.0, -0.0,}; double fmod(double x, double y) { @@ -140,7 +140,6 @@ double fmod(double x, double y) lx = hx>>(n-32); hx = sx; } INSERT_WORDS(x, hx|sx, lx); - x *= one; /* create necessary signal */ } return x; /* exact output */ } -- cgit v1.2.1
