Ouch! need to clarify that a bit.
When comparing with the numeric operators, Perl converts strings to numbers
using something like the atof(3) function (maybe it actually uses atof(),
I'm not sure). So the numeric value of a string is determined by skipping
any leading whitespace and examining characters until the first unrecognized
character is found. If no characters that look like a number are found, 0 is
returned.
The following numeric comparisons are all TRUE:
"123" == 123
" 123" == 123
"123.0" == 123
"1.23E2" == 123
"123 Main Street" == 123
