Rounding Formula

The formula for rounding is more like a set of logical operators. For example, if you have a number, say 5.6, in the form x.y, the logical operators are as follows:

  • If y is >5, return X+1
  • If y is <5, return X

This can be done for any number of decimal points using the same method.
