Question : need to Trim and cast a string as a number

I have a field with a qty and unit of measure expressed as a single string. (eg 25CS or 500SL).
The QTY could be any length, but the Unit of measure is always 2 char at the end.  I need this to be a proper number so it can be used in other formaulas

How do I trim off the 2 right characters and cast as a number?

Answer : need to Trim and cast a string as a number

in crystal this would remove the last two chars

Mid ({yourfield},1 ,Length ({yourfield})-2 )

you can convert to number by

cdbl(Mid ({yourfield},1 ,Length ({yourfield})-2 ))
