PHP Round Up Question

Hey guys,

I'm working on an OpenCart store but my client's being picky and wants numbers rounding up to 50p (we're in the UK).. so for example, £3.03 would be £3.50.. and £6.67 would be £7.00

Now I've found the bit of code that I need to replace..

    $string .= number_format(round($value, (int)$decimal_place), (int)$decimal_place, $decimal_point, $thousand_point);
    ``` 

and i've changed it to

 ```php
    $string .= number_format(ceil($value), (int)$decimal_place, $decimal_point, $thousand_point);
    ``` 

Which rounds it from £42.01 to £43.00 instead of £42.50... Does anyone know how to adjust it to make it go to .50 instead of the next pound?

Many thanks!

Ben

It is a bit of a work-around solution, but if you multiply by two, round to the nearest £, then divide the result by two, then you'll have your number rounded to 50p:

    $string .= (2 * number_format(ceil($value), (int)$decimal_place, $decimal_point, $thousand_point))/2;

Something like that. Give it a go.

Thanks John, turns out my client wanted it rounded up to the nearest 5p not 50.. so I rejigged and came up with this function that did the trick...

function roundFive($v) {

        return ceil($v*20) / 20;
}
