Subject: Thoughts on Feature Request - Arithmetic
From: nrixham@gmail.com (Nathan Rixham)

In-Built PHP Functions for parsing of basic arithmetic and if possible 
fraction to decimal and decimal to fraction

$arithmetic_string = "3*5";
echo arith($arithmetic_string); // returns float 15

$arithmetic_string = "1/2";
echo arith($arithmetic_string); // returns float 0.5

$fraction_string = "1/4";
echo fracdec($fraction_string); // returns float 0.25

$dec_string = "0.5";
echo decfrac($dec_string); // returns string "1/4"

I've used php for years, came accross the need for this today and was 
suprised such a basic command wasn't there.. currently the only way I 
can see to do it would be to eval.. which isn't the most secure method 
for such a basic need.

Regards

Nathan
