| 426532 | 2006-02-03 00:17:00 | Hi all I need to calculate GST using PHP and am a bit stuck Heres the problem, lets say i have $900 GST inclusive and want to work out... the price without GST and the amount of GST charged ok to work this out I would normally just do the following Price without GST = 900/1.125 = $800 Gst Content = 900 - 800 (Price without GST) = 100 As is usual with PHP my phobia of Div and Mod cause me to end up with weird answers, everyone has their pet bugbears and div & mod are mine any help would be greatly received |

No you haven't thats exactly what i should have done For some strange reason i got it into my head to use div and mod, and didn't even try the obvious Thanks |
