Multiplies x by 2 raised to the power of n.

If x is an integer, this function is the equivalent of an arithmetic shift. The connector pane displays the default data types for this polymorphic function.

Details  Example

n can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on. If n is a floating-point number, this function rounds n before it scales x (0.5 rounds to 0; 0.51 rounds to 1). If n is a 64-bit integer, LabVIEW coerces n to a 32-bit integer.
x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
x*2^n is the result of multiplying x by 2, raised to the power of n.

Scale By Power Of 2 Details

If you wire a fixed-point value to this function, the resulting output value retains the fixed-point configuration settings of the input value. However, the value is likely to quantize or overflow.

Example

Refer to the Add - Various Uses VI in the labview\examples\general\functions\Numeric directory for an example of using the Scale By Power Of 2 function.
