    Rounding mode to round away from zero. If you want strict rounding, consider working with numeric types consistently. 5.25% of Amount One: 26.98 If it’s 0, then the number should always be rounded down.

RoundingMode.HALF_DOWN works the same as RoundingMode.HALF_UP when the last decimal that decide the rounding is 5. A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. Either you perform the rounding prior to Informatica software, or you use some programmed code (Custom Transformation / Custom Function / Java Transformation) to perform this rounding on the "raw" strings which contain the numbers. If we divide the number 15 by the number 4, we know the result would be 3.75. * 
 They have something that we can use called “bankers rounding,” aka “round-half-to-even”. This means that mid point values are rounded towards the nearest even number.
