Owning Class: bitwise

Requires: MathScript RT Module

Syntax

d = bitshift(a, b)

d = bitshift(a, b, c)

Description

Performs a bitwise shift on the input elements. For example, if a = 9 (1001), bitshift(a, 1) = 18 (10010) and bitshift(a, 1, 4) = 2 (0010).

Examples

Inputs

Name Description
a Specifies a scalar, vector, or matrix of nonnegative integers. All elements of a must be less than maxfloatint.
b Determines the shift sizes. Shifting a by b bits is equivalent to multiplying a by 2^b and then rounding to the nearest integer. b is a scalar, vector, or matrix of integers. b is the same size as a unless a or b is a scalar.
c Specifies the number of valid bits for each of the shifted integers. If the shifted integers exceed c bits, LabVIEW ignores the overflow. c is a matrix of integers. The default is 53.

Outputs

Name Description
d Returns the elements of a shifted to the left by b bits. d is a matrix of the same size as the larger of a and b.
