{{alias}}( x, n, b )
Rounds a numeric value to the nearest multiple of `b^n` toward zero.
Due to floating-point rounding error, rounding may not be exact.
Parameters
----------
x: number
Input value.
n: integer
Integer power.
b: integer
Base.
Returns
-------
y: number
Rounded value.
Examples
--------
// Round to 4 decimal places:
> var y = {{alias}}( 3.14159, -4, 10 )
3.1415
// If `n = 0` or `b = 1`, standard round behavior:
> y = {{alias}}( 3.14159, 0, 2 )
3.0
// Round to nearest multiple of two toward zero:
> y = {{alias}}( 5.0, 1, 2 )
4.0
