$sqrt returns the square root.
Synopsis[edit]
$sqrt(<N>)
Parameters[edit]
- N - Number for which the square root is returned
If N is negative, returns $null. You can use the letter 'e' or 'd' as *10^N, $sqrt(5e6) = $sqrt($calc(5*10^6))
Square Root is limited to 6 decimal places. When squared, it often has a rounding error difference from the original N.
Example[edit]
//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
Compatibility[edit]
Added: mIRC v5.3
Added on: 13 Dec 1997
Note: Unless otherwise stated, this was the date of original functionality.
Further enhancements may have been made in later versions.
