Owning Palette: Numeric Functions

Requires: Base Development System

Returns the absolute value of the input.

The connector pane displays the default data types for this polymorphic function.

Details  Example

x can be a scalar number, a fixed-point number, an array or cluster of numbers, an array of clusters of numbers, and so on. x cannot be an unsigned integer, because unsigned integers represent only non-negative integers.
abs(x) is the absolute value of x. When x is of the form x = a + bi, that is, when x is complex, the following equation defines abs(x):

Absolute Value Details

When you wire matrix data as an input to this function, a VI that includes subVIs that work with the matrix data type replaces the function. The resulting VI has the same icon but contains a matrix-specific algorithm. The node remains a VI if you disconnect the matrix from the input(s). Wire other data types as inputs to restore the original function. If you wire a data type to a function and that data type causes a basic math operation to fail, the function returns an empty matrix or NaN.

Example

Refer to the Numeric Functions VI in the labview\examples\Numerics directory for an example of using the Absolute Value function.
