Rounding by adding or subtracting 1 unit to the highest or lowest value item in list until row totals 100
List<decimal> numlist = new List<decimal>(); numlist.Add(50.2m); numlist.Add(40.6m); numlist.Add(9.0m); decimal diff = 100.0m - numlist.Sum(); //This is set because the value should be only 1 decimal place int update = Convert.ToInt32(diff / .1m); if (update > 0) { for (int x = 0; x < update; x++) { numlist[x % numlist.Count()]...

Rounding numbers to two decimal places in Java
I would test the distance with the standard rounding, then adjust and round again : for (String string : new String[] {"1.1245", "1.1244", "1.1235", "1.1249", "1.1299"}) { BigDecimal a = new BigDecimal(string); if (a.setScale(2, BigDecimal.ROUND_HALF_UP).subtract(a).compareTo(new BigDecimal("-0.0044")) < 0) { System.out.println(string + ":" + a.add(new BigDecimal("0.001")).setScale(2, BigDecimal.ROUND_HALF_UP)); } else { System.out.println(string...
Trying to mimic Excel rounding is causing me grief

First: The problem is hard. Because 4.53/2 = 2.265. This rounds to 2.27. However the tiniest rounding error in the calculation resulting in a smaller result (2.264999999....) will lead to a rounding to 2.26. This is what is happening here. To solve this problem you need to have a floating...

This is a weird restriction, but you could do this: x = str(x) dec_index = x.find('.') tenth_index = dec_index + 1 tenth_place = x[tenth_index] # will be a string of length 1 should_round_up = 5 + tenth_place.find('5') + tenth_place.find('6') + tenth_place.find('7') + tenth_place.find('8') + tenth_place.find('9') print int(x[0:dec_index]) + should_round_up What...
What is HALF_EVEN rounding for? [closed]
It is useful when you are performing multiple rounding operations and want the cumulative result to be a true average, and not skewed up or down, as it would be with HALF_UP or HALF_DOWN. Specifically, it is useful for statistical analysis (you don't want the results polluted by a non-random...
PHP: rounding a number into 16 decimal digits
php,floating-point,decimal-point,number-rounding
You can set this parameters at run-time. 16 digits is usually the maximum value on most platforms, larger values giving only meaningless or "fictional" digits: ini_set("precision", "16"); See Changing precision level floating-point variables...
RoundingMode.HALF_DOWN issue in Java8
java,java-8,rounding,number-rounding
Seems that it's intended change. The JDK 1.7 behavior was incorrect. The problem is that you simply cannot represent the number 10.55555 using the double type. It stores the data in IEEE binary format, so when you assign the decimal 10.55555 number to the double variable, you actually get the...
