i tried using the SQR function in VB,and it gave me a wrong answer. i did some search and i got this:

# SQR
The square function returns the square (ie the argument multiplied by itself) of its supplied argument,


SQR( 2 ) returns 4

# SQRT
This function returns {always returns a real} the square root of its argument, eg,


SQRT( 4 ) returns 2.0000000000E+00



could someone explain how would i use each of these two functions in VB?
