I'm learning JavaScript, and I've heard that there can be issues among different browsers when using JavaScript's Math.round() and .toFixed() methods. After researching on this website, the solution I've with the seen with least criticisms are the Decimal Rounding method as illustrated at the MDN. Looking over the code, I'm...

This is an easy one. But anyway, I think it is a good idea to have this question answered here for a faster, easier reference. This operation: (/ 3 2) yields this: 3/2 I need one function to round up, which would yield 2 and another one to round down,...

I'm using the ng-currency library - http://aguirrel.github.io/ng-currency/ - to display currency values in a project.

I want to round off the number with exact value of decimal in PHP. Eg: 1.399 => 1.39 or 363.3 => 363.30 I have used printf("%.2f", 1.399) and number_format((float)$a,2,'.','') but the answer is 1.40 which is incorrect for me....

I'm wondering how to round a number in python while using string formatting. In my code, I used %r instead of %d, beacuse %d prints an interger. How do I round the numbers while using %r? I would like to have my numbers rounded to two decimal places. def new_formula(value):...

I have the same question as the question here. The user asked: I just wrote this to return the nearest 45 degree angle. Like 0, 45, 90, 135... It feels like there must be a better way of doing this though. This is working fine but it looks messy. public...

Does anyone know why the pmulhrsw instruction or _mm_mulhrs_epi16(x) := RoundDown((x * y + 16384) / 32768) always rounds towards positive infinity? To me, this is terribly biased for negative numbers, because then a sequence like -0.6, 0.6, -0.6, 0.6, ... won't add up to 0 on average. Is this...

Is there an optimized, performant way to round a double to the exact value nearest multiple of a given power of two fraction? In other words, round .44 to the nearest 1/16 (in other words, to a value that can be expressed as n/16 where n is an integer) would...

I'm taking a Python course at Udacity, and I'm trying to work this out for myself without looking at the answer. Perhaps you can give me a hint for my logic? Below are the instructions and what I have so far. We haven't learned conditional statements yet, so I can't...

int a, b, c = 0; c = (a+b)/2; In this code, if both "a" and "b" are even (Example 1), then there's no problem. But if one of them is odd (Example 2), then the answer will have +0.5. I want to round it up. Example 1. a=4, b=10...
