$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
