    How do I use mathematical operators?

    I want to use math functions as pow and sqrt.

    When i try to do that (including math.h) I get an error msg saying that these operator are double and i'm performing a calculation with integers

    Any ideas?

    You could try following the advice of the errors. Either declare the variables that you want to use the math functions on as double, or cast the result of the functions to int, like so:
    Code:
    int x = 256, result;
    
    result = (int)sqrt(x);
    -Prelude
    My best code is written with the delete key.

    Thx man

    I used casting as

    int x;
    double approx_x;
    approx_x=double(x);

    Thanks
