How do you round negative decimals?

If the fractional portion of number is 0.5 or greater, the argument is rounded to the next higher integer. So when the fraction is exactly 0.5 , it rounds up. For a negative number, this means it rounds closer to 0, for a positive number it rounds away from 0. So -0.5 rounds to 0 , while 0.5 rounds to 1 .

Can you round off negative numbers?

If x is positive, round-down is the same as round-towards-zero, and round-up is the same as round-away-from-zero. If x is negative, round-down is the same as round-away-from-zero, and round-up is the same as round-towards-zero. In any case, if x is an integer, y is just x .
