Sqr
Returns a square root of a number
result = Sqr( number )
number
Returns the square root of the argument number.
If number equals zero, Sqr returns zero.
If number is less than zero, Sqr returns a special value representing "not defined", printing like "NaN" or "IND", exact text is platform dependent.
This is the same as raising the argument number to the one-half power: y = x ^ (1/2) . The required number argument can be any valid numeric expression greater than or equal zero.
The output would look like:
Syntax
Usage
result = Sqr( number )
Parameters
number
the number (greater than or equal to zero)
Return Value
Returns the square root of the argument number.
If number equals zero, Sqr returns zero.
If number is less than zero, Sqr returns a special value representing "not defined", printing like "NaN" or "IND", exact text is platform dependent.
Description
This is the same as raising the argument number to the one-half power: y = x ^ (1/2) . The required number argument can be any valid numeric expression greater than or equal zero.
