Folks,

Say I have the string "20.304000". How can I eliminate the last 3
zeros?

Thanks.

Dear K

we have a routine in our library named number_format which is able to print
numbers without the fullfillings of 0.

http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/download/number_format.tar.gz
or as idl binary
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/download/number_format.sav

print,number_format(20.304000)
20.304

You can use this routine to format an array of numbers to the same length
too.

a=[20.1,20.134,8.98]
print,transpose(number_format(a))
20.100
20.134
8.980

Further routines and licensing you find here

best regards
