Hello folks,

surprisingly to me the following string comparison of two numbers in different format (scientific, decimal) works as if not the operator "eq" but "==" would have been used for the comparsion, i.e., the variables $a and $b are compared numerically.

I would have expected that the numbers would have been converted to strings (due to the eq-operator) and that the result would be "Numbers are not equal!".

So, why does "eq" work like this and can I rely on this in general, i.e., would two numbers always numerically oompared by "eq" (e.g., it works for the two numbers 1000000 and 1_000_000 in the same manner).

perl -e '$a = 1e-3; $b = 0.001; if ( $a eq $b ) { print "Numbers are e
+qual!\n" } else {  print "Numbers are not equal!\n" }'
Numbers are equal!
