Tanh v0.1.0
Returns the hyperbolic tangent.
Package: Math
Signature
func Tanh(x: float64) -> float64;
func Tanh(x: float32) -> float32;
Parameters
| Name | Type | Description |
|---|---|---|
x | float64 / float32 | Any value. |
Returns
The hyperbolic tangent of x, in the range (-1, 1). Tanh(±0.0) is
±0.0, preserving the sign, and Tanh saturates to ±1.0 once |x| is
large enough that the distinction is no longer representable. A NaN argument
propagates.
Example
import Math::Tanh;
func Main() -> int {
let a = Tanh(0.0); // 0.0
let b = Tanh(1.0); // 0.7615941559557649
return 0;
}
