$sqrt identifier - mIRC
< mirc‎ | identifiers

$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
