In order to determine whether a rounding operation involves a midpoint value, the Round method multiplies the original value to be rounded by 10 n, where n is the desired number of fractional digits in the return value, and then determines whether the remaining fractional portion of the value is greater than or equal to .5.

If we want to round to a set number of decimal places, then we have to handle that ourselves. I have a calculation entered as Simplified Field Notation for a field on an interactive pdf where a user can enter values and the form auto-calculates other fields based on what is entered.- AcrobatUsers Community Expert - Contact me personally at What am I doing wrong? Note that as numbers in JavaScript are IEEE 754 floating point numbers with round-to-nearest-even behavior, the ranges claimed for the functions below (excluding the one for Math.random() itself) aren't exact. E.g. The Overflow Blog Syntax.



Math.min(0, 150, 30, 20, -8, -200);  // returns -200 Examples might be simplified to improve reading and basic understanding. Because floor() is a static method of Math, you always use it as Math.floor(), rather than as a method of a Math object you created (Math is not a constructor). The "simplified field calculations" is very limited as to what field names can be used and there is no way to use a field's properties or methods or call a function, so you will need to use a more complex JavaScript to perform the rounding.
