[gradsusr] Rounding Numbers With Decimals

[Jeff Duda]

Anytime you use a script written by another person and you run into
problems, it's generally easiest and best to ask the script author since
they know the script better than anyone else.

However, from what you attached, I can see that you should probably use the
math_fmt() function instead to format the string of the value.  Use it to
reformat min_val before the second draw string command for each of the high
and low.
