Hi All,
I wanted to check whether the user input is only a number and does contain any alphabet/s anywhere i.e. starting, end or in-between. Can somebody tell me how to do this?
How about simply m/^\d+$/
Yeah, that works. I guess I like recommending Regexp::Common because it's standard and becuase it's more flexible and robust:
use Regexp::Common qw(number);
/^$RE{num}{int}{-sep=>',?'}$/
and print "An integer with optional comma seperator."Use the Regexp::Common module:
