x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.

x^2 is of the same numeric representation as x. Note  You can manually configure this function to output data of a type you want. To specify the output data type, right-click the function and select Properties to display the Object Properties dialog box. On the Output Configuration page, click the Representation icon and select the data type you want. A blue coercion dot appears on the output terminal of the function to indicate that you have configured the output data type.

Square Details

If you wire fixed-point values to Numeric functions such as Add, Subtract, Multiply, and Square, the functions usually return values that do not lose any bits of word length. However, if the operation creates a value that exceeds the maximum word length that LabVIEW accepts, overflow or rounding conditions can occur. LabVIEW accepts a maximum word length of 64 bits. Use the Numeric Node Properties dialog box to configure how LabVIEW handles overflow or rounding of fixed-point data.

Example

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