SQR


Returns a square root of a number

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 domain error (-1.#IND).

Description:
This is the same as raising the argument number to the one-half power ( ^ 1/2). The required number argument can be any valid numeric expression greater than zero.

Examples:
Dim a As Single
Dim b As Single

Input "Please enter one side of a right triangle: ",a
Input "Please enter another side of a right triangle: ",b
Print ""
Print "The hypotenuse of the triangle has a length of"; Sqr ( a * a + b * b )

Sleep


The output would look like:
Please enter one side of a Right triangle: 3
Please enter another side of a Right triangle: 4
The hypotenuse of the triangle has a length of 5
