syntax for math operations?

[AsianSensation]

how do you use mod and exponents in c++?

*mod as in modular math.

[Catalyst]

mod is %
and exponent is the function float pow(float num,float exp) in <math>
avoid pow whenever necessary it can be very very slow (i.e use x*x*x over pow(x,3))

[AsianSensation]

so if I want to check if a number is a divisor of another, I do this?

code:

if (num % 5 == 0)     blah blah blah

[Catalyst]

yup just like that

[AsianSensation]

cool, thanks Catalyst.

I have another question, how about the square root syntax, and does anyone know a site where I can get a list of the syntax and their uses?

[Mazer]

www.cppreference.com

[Catalyst]

Square Root is just float sqrt(float n)

heres another good site:

www.cplusplus.com

[AsianSensation]

cool, thanks guys.

indeed those sites will help negate the AWESOME UNQUESTIONABLE GREATNESS of my comp sci teacher

cppreference.com sux, it dont give u much info on the functions...

[naoki]

considering the purpose of the site and the lack of any advertisement or help to fund the site, i think cppreference is pretty damned nice to pay for its domain for the content it gives.

also try cprogramming.com and codenewbie.com
