[quote] I don't quite understand your problem, but I use integers for any monetary workings as you can guarantee it is accurate (obviously, you work in pence or cents rather than GBP or USD).
Alex Hello Alex, I was reading through this thread, and I was curious about what methods you use to handle fractions of a dollar and/or fractions of a penny if you are always using integers. Do you only use a decimal for printing? do you adjust all interest rates, etc...then as well? How about when interest calculations result in fractions of pennies, how do you handle it then? Basically, I can't see how it could be done with just integers alone? thanks dank [/quote] To be honest, I haven't used it for any complicated use - shopping carts are additive contraptions. However, I don't see the problem. 1) I use Smarty a lot - I use a plugin to format the integer to a price (ie divide by 100 and display in 2 decimal places). So yes, I only put the decimal place there to print. 2) Why do interest rates need to be changed?? Take £123.45 @ 5%. 123.45 * 1.05 = (12345 [pennies] / 100) [pounds] * 1.05 = (12345 * 1.05) / 100 Same calculation in my mind!! (Tell me if I have missed the point!!) 3) If you have a fraction of a penny - round it!! Surely, that's what the banks do!! It's a penny!! I think it can be done with integers alone - let me know if you disagree!! Alex No virus found in this outgoing message.
