FW: Square root

[Holland, Michelle]

Hi Mike,

You can calculate roots by using fractional exponentiation (^0.5).  For
example:

SCREEN screenname
FILE filename
TEMP x
TEMP y
FIELD x
FIELD y
PROC DES calc NODATA
BEGIN
LET y = x^0.5
DISPLAY y
END
BUILD

Start the screen, enter a value in X, go back to the Action field and enter
"calc" & you will see the square root of X in Y.

You can also do the cube root:

y = x^(1/3)

I was wondering if anyone knows of a QDESIGN technique to get the square
root of a number. As far as I can see there is no existing Powerhouse
function that does this. Please feel free to correct me if I'm wrong.

Thanks in advance for any help.
