How to round to the nearest hundredth in c++
Webround ( ) function in C returns the nearest integer value of the float/double/long double argument passed to this function. If decimal value is from ”.1 to .5″, it returns integer value less than the argument. If decimal value is from “.6 to .9″, it returns the integer value greater than the argument. To do it generically, use the same function you've got, but shift the input up or down some decimals: double round ( double value, int precision ) { const int adjustment = pow (10,precision); return floor ( value* (adjustment) + 0.5 )/adjustment; } (Note that you'll have to #include or #include to use the pow function.
