$ perl -le'
for ( 7, 5.9 ) {
print "$_ is an integer" if $_ == int;
}
'
7 is an integer
Also have a look at this FAQ:
Hi Jerry
Just check for the existence of a decimal point:
if ($n =~ /\./) { print "Floating point\n" }
else { print "Integer\n" );
( This will work even if you have assigned $n = 7.000, but assumes that $n
is at least numeric and isn't so large or small that it's in scientific
notation )
Hi!
I am looking for a simple way to figure out if a value is a integer or a
float. How to tell the difference between 7 and 7.5.
Thanks,
Jerry
