Round

Rounds to the nearest integer.

Round(X)

In Analytica 4.1, to round to a given number of digits, i.e,. to the nearest power of 10^-digits, use:

Round(X,digits)

Round(X,digits) cannot guarantee that the result can be represented exactly as a power of 10. Analytica represents numbers using a binary floating point format. Fractions that are an exact power of 10^-1 cannot always be represented exactly in binary -- i.e., they are usually not an exact power of 1/2. Therefore, non-zeros may be observed around the 16th significant digit. The number returned is a number that is as close to the rounded value as can be represented in an IEEE floating-point binary format. Rounded values generally will display as expected in result tables unless you have the number format set to show more than 15 significant digits.
