Abs gives us the absolute value
eg
abs (-12)=12
abs(12.24)=12.00

The rounding of depends on the precision. Have never peeped into all this stuff. But floats have precision upto 6 decimals. And if you need to print say floats in 2 decimals, u can use %.2f as format specifier

I know this in C++..inclue the math.h
cout.precision(2);
cout<<1.2345;
OUTPUT
1.23

Clear?

You can use the floor and ceil function also to control the round off to next higher or lower digit.
