math question

[youngun]

I tried to calculate monthly payment using Sybase but kept getting errors. Here is the formula:

p*i/[12*(1-[1+(i/12)]^-n)]

p*i = 5473.6
n = 36
i = 2.5

but i keep getting arithmetic overflow error, or truncation error when using the POWER() function. Can somebody please tell me what to do, or provide the code? Thank you very much.

boil down your sql to the simplest example that errors out, then fix it.
