The fractional part x - floor(x), always in [0, 1) for finite x. For a negative x this is not the part after the decimal point: frac(-1.25) is 0.75. Only float and float64.
assert(frac(2.25) == 0.25 && frac(-1.25) == 0.75 && frac(3.0) == 0);frac :: (x: $T) -> TThe part of x above its floor, in 0..1. Negative values wrap up, so -0.25 gives 0.75.
Parameters
- x: $T
- the value.
Returns
- T
