Never mind.  I figured it out using substr().

Thanks,

Subject: replacing numbers around a decimal


I am creating a little calculator that is going to need to take a user
entered number that will always have 2 decimal places (using sprintf).  It
could be 89562321.29 or it could be 101.00) and take the last 4 digits (with
the period included, so five places) and do two things: 

1)Store the number in a variable.  For the two examples above that would be
21.29 and 01.00 respectively would be stored in their own variable x=21.29
or it could be x=01.00; and 

2) replace the last 4 numbers (5 places) with 00.00 -- always.  For the two
examples above they would become 89562300.00 and 100.00.  Can anyone point
me in the right direction?

Thanks,
Andrew
