How about that?
Pay attention, it's C rather than C++. So 5 times shorter :-)
It's not the fastest for big x/y ratios, but rather simple and not
*too* slow. At least as long as hardware supports FMA.
For small x/y ratios it should be pretty close to best possible.
#include <math.h>
#include <fenv.h>
double my_fmod(double x, double y)
{
if (isnan(x))
return x;
// pre-process y
if (isless(y, 0))
y = -y;
else if (isgreater(y, 0))
;
else {
if (isnan(y))
return y;
// y==0
feraiseexcept(FE_INVALID);
return nan("y0");
}
// y in (0:+inf]
// Quick path
double xx = x * 0x1p-53;
if (xx > -y && xx < y) {
// among other things, x guaranteed to be finite
if (x > -y && x < y)
return x; // case y=+-inf covered here
double d = trunc(x/y);
double res = fma(-y, d, x);
if (signbit(x) != signbit(res)) {
// overshoot because of unfortunate division rounding
// it is extremely rare for small x/y,
// but not rare when x/y is close to 2**53
res = fma(-y, d+(signbit(x)*2-1), x);
}
return res;
}
// slow path
if (isinf(x)) {
feraiseexcept(FE_INVALID);
return nan("xinf");
}
int oldRnd = fegetround();
fesetround(FE_TOWARDZERO);
double ax = fabs(x);
do {
double yy = y;
while (yy < ax * 0x1p-1022)
yy *= 0x1p1021;
do
ax = fma(-yy, trunc(ax/yy), ax);
while (ax >= yy);
} while (ax >= y);
ax = copysign(ax, x);
fesetround(oldRnd);
return ax;
}
