How to round products price?

Question

I have installed Price Rounding plugin to my Magento site.

It works good, but I need to round price like that: 131.26 -> 131.25

The plugin gives me that: 131.26 -> 131.00

I know that it uses PHP math functions, but I don't know is there some PHP math functions that can give me 131.25 result.

Maybe there is another way to round price?

Answer 1

To round prices as .00 .25 0.50 0.75 you can use the following function:

function round_quarter($price){
  return round($price * 4) / 4;  
  // also possible floor($price * 4) / 4;
  // it depends on your business logic.
}

to check how it works try:

echo round_quarter(131.26);
