ArcSin v0.1.0
Returns the inverse sine, in radians.
Package: Math
Signature
func ArcSin(x: float64) -> float64;
func ArcSin(x: float32) -> float32;
Parameters
| Name | Type | Description |
|---|---|---|
x | float64 / float32 | A value in [-1, 1]. |
Returns
The angle in [-HalfPi, HalfPi] whose sine is x. ArcSin(±1.0) is
±HalfPi. For |x| > 1.0 the result is a NaN, since no real angle has that
sine; a NaN argument also propagates.
Example
import Math::ArcSin;
func Main() -> int {
let a = ArcSin(1.0); // 1.5707963267948966 (HalfPi)
let b = ArcSin(0.0); // 0.0
return 0;
}
