abs

The absolute value. For s8, s16, s32 and s64 it asserts on the most negative value, which has no positive counterpart. For float and float64 it clears the sign bit, so abs(-0.0) is +0.0, abs(-infinity) is infinity and a NaN keeps its payload. Vectors take the absolute value of each component.

assert(abs(-5) == 5 && abs(7) == 7);
assert(abs(-2.5) == 2.5);
assert(abs(xyz(-1, 2, -3)) == xyz(1, 2, 3));

abs :: (x: $T/ .[s64, s32, s16, s8]) -> T

abs :: (x: float64) -> float64

abs :: (x: float32) -> float32
