Square Root '^^'

The Square Root operator returns the square root of a value. Square Root can be used in both variable and constant expressions. When used with variable expressions or integer constant expressions, Square Root returns the 32-bit truncated integer result. When used with floating-point constant expressions, Square Root returns the 32-bit single-precision floating-point result. Example:

X := ^^Y

Square Root becomes an assignment operator when it is the sole operator to the left of a variable on a line by itself. For example:

^^Y 

This would store the square root of the value of Y back into Y.
