In plain English, here is what the code tries to do:

Examine the value of $_
Check if it contains a decimal number, or an integer
If it does, assign those values to $whole and $deci

The expression used does handle boundary conditions, which is what make it appear complex.

It accurately evaluates numbers like 324 44.55 44. .44 and 0.445
