How do you round 2.037?

Answer 1

It depends on how many digit you want to round off.

When truncating a number, just chop off the last digit and the resulting value is a truncated number.

To round of a number, examine the last digit. If it is less than 5, just eliminate it otherwise the last digit is 5 or more, drop the digit and increase the remaining last digit by 1.

2.037 rounds off to 2.04 since the last digit (7) was greater 4.

2.04 rounds to 2.0 (or 2) since the last digit is less than 5.
