How about this?
J
uint64_t float64_to_uint64 (float64 a STATUS_PARAM)
{
uint64_t res;
int64_t v;
if (isinf(a) || isnan(a)) {
return special value ( maybe 1<<63 ?)
}
else
if (a < 0.0 || a > (float64)UINT64_MAX) {
return out-of-range value, whatever that is
} else {
a += (float64) INT64_MIN; // move a downwards
v = llrint(a); // convert
v -= INT64_MIN; // move v back up
return v;
}
}
