$sqrt returns the square root.
Synopsis
$sqrt(<N>)
Parameters
N Number for which the square root is returned
If N is negative, returns $null.
Square Root is limited to 6 decimal places. When squared, it often has a rounding error difference from the original N.
Example
//echo -a $sqrt(3) is the same as $calc(3^.5) ; returns: 1.732051 is the same as 1.732051
//var %i 7 | echo -a $calc( $sqrt(%i) * $sqrt(%i) ) ; slight rounding error due to decimal limited to 6 places: 6.999998
