    Yup!

    Code:
    printf("%.2f", answer);
    Limits the answer to 2 places after the decimal point.

    thanks but....

    Yeah thanks but there is a slight problem. I don't know how many figures are going to be behind the decimal place (eg. the answer could be 5, 5.2, 5.6545, 5.364 etc.) so is there a way just to take off the useless and annoying zeros (eg. instead of having 5.3640000 have 5.364)????

    Thanks

    Code:
    printf("%g", answer);
