error C2296

Jul 24th, 2008

hi!

ive compiled a program that gives me this error:
(88) : error C2296: '%' : illegal, left operand has type 'float'
(94) : error C2296: '%' : illegal, left operand has type 'float'
(100) : error C2296: '%' : illegal, left operand has type 'float'

thing is that i have all variables defined as float, and that shouldnt be a problem, right??

You can't do modulo on floats.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
Do not PM me for help; You'll be ignored, or told to learn to read.
Do not ask me if I'm muslim - I'm not. Nor do I care about yours or anyone else's mysticism. Religion is a matrix, take the RED PILL.

FYI, the bold tags don't work with C++ style code tags. They DO work with non-specific code tags:

[code]
// paste code here. Can put bold highlighting.
[/code]

The C++ highlighting seems to override the manual bold text highlighting, so [b] is not parsed as "bold tag", but is assumed to be part of the code itself. I see you are referring to lines 7, 13, and 19. Your problem is here:

((peso - 1000)%500)

If peso is a float, then peso - 1000 is a float. The mod operator is looking for an integer on the left and the right of the % operator.

If you are looking for a remainder and peso needs to be a float, consider fmod from cmath.
