Scale By Power Of 2 Function

Owning Palette: Numeric VIs and Functions

Requires: Base Development System

Multiplies x by 2 raised to the power of n.

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

	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 truncate or wrap.
