{{alias}}( b, x )
Evaluates `bˣ - 1`.
When `b` is close to `1` and/or `x` is small, this function is more accurate
than naively computing `bˣ` and subtracting `1`.
Parameters
----------
b: number
Base.
x: number
Exponent.
Returns
-------
y: number
Function value.
Examples
--------
> var y = {{alias}}( 2.0, 3.0 )
7.0
> y = {{alias}}( 4.0, 0.5 )
1.0
> y = {{alias}}( 0.0, 100.0 )
-1.0
> y = {{alias}}( 100.0, 0.0 )
0.0
> y = {{alias}}( 0.0, 0.0 )
0.0
> y = {{alias}}( {{alias:@stdlib/constants/float64/pi}}, 5.0 )
~305.0197
> y = {{alias}}( NaN, 3.0 )
NaN
> y = {{alias}}( 5.0, NaN )
