Rounding down numbers using decimels

Question

HiI am struggling to round down decimel numbers in fields to prevent the default to round up - ie: if I have 4 decimel places: 0.0000 and I type in 0.34567 - I need the field to round down the nearest decimel point: 0.3456 rather than the default of rounding up to 0.3457.  Is there a way I can do this in acrobat?

Place the function as a doc-level script, and as the custom validation or calculation script of the field enter this:if (event.value) event.value = roundDown(Number(event.value), 4);

You can use this function to do it: function roundDown(v, nDecimals) {return Math.floor(v * Math.pow(10, nDecimals)) / Math.pow(10, nDecimals);} And you then call it like this: roundDown(0.34567, 4);
