nextpowerof2 (MathScript RT Module Function)
Owning Class: basic
Requires: MathScript RT Module
Syntax
c = nextpowerof2(a)
Legacy Name: nextpow2
Description
Computes the first power of 2 that is not smaller than abs(a). More precisely, p = nextpowerof2(a) if 2^p>=abs(a) and p is minimal.
Inputs
| Name | Description |
|---|---|
| a | Specifies a scalar, vector, or matrix of double-precision, floating-point or complex double-precision, floating-point numbers. If a is a vector, nextpowerof2(a) is equivalent to nextpowerof2(length(a)). |
Outputs
| Name | Description |
|---|---|
| c | Returns the first power of 2 that is not smaller than abs(a). c is a scalar. |
Examples
A = 7.3
C = nextpowerof2(A)
