Doesn't this pattern already cover all possible cases of `value` needed?
void f(double value)
{
auto lvalue = cast(long)value;
if (lvalue == value) // `value` lacks fraction and in range
[long.min .. long.max]
{
// use long lvalue
return;
}
// use double value
}
Sure. You don't even need to use isFinite like I wrote above because
special values like inf and nan become some long values and will never
equal to itself.
Your question motivated me to do a little workout for my brains. Sorry
if it confused you.
