Same for std.math.lround
they use the FP way while for float and double it's only one
sse instruction. Typically with 6 functions similar to this one:
int round(float value)
{
asm
{
naked;
cvtss2si EAX, XMM0;
ret;
}
}
we could get ceil/trunc/round/floor, also almost as easily
fmod, hypoth.
classic but I dont get why thery're not in std.math.
Goddamnit, we're in 2016.
lround and friends have been a big performance problem at times.
Everytime you can use cast(int) instead, it's way faster.
