Most of us are uncomfortable with using fractions when writing programs. If we encounter a fraction, we will first convert it into a floating point number (with decimals) and proceed from there. Most programming languages would prefer to use 0.5 as opposed to 1/2 because the later might conflict with the syntax of the languages. In this article, I will discuss my attempt to work with fractions in one of the PHP projects that I have done.

They start with the CSS to handle the output before moving into the PHP code. The code given will take in a decimal number and do its best to match it up with a fraction string value out of an array. The result is the echoed out with sup and sub tags to create the correct effect.
