The cbrtf, cbrtl, cbrt, cbrtd32, cbrtd64, and cbrtd128 subroutines compute the real cube root of the x argument.
Item | Description |
---|---|
x | Specifies the value to be computed. |
Upon successful completion, the cbrtf, cbrtl, cbrt, cbrtd32, cbrtd64, and cbrtd128 subroutines return the cube root of x.
If x is NaN, an NaN is returned.
If x is ±0 or ±Inf, x is returned.
