check for "within range"

jcferguson

Hi All,

is there an easy way to check if a variable is within a range of another variable? so for example I want to check to see if x is within 10 of y. Would I use:

if abs (x-y) > 10 then
do something
else
don't do something.

?

Thanks

You've got it. The only time this won't work is if the values are widely different (more than 15 bits difference) in which case you might run into problems with the limited word size in comparing them. It doesn't sound like this is the case here.
