Why is rounding done like this? [on hold]
You should have a look at how floats are handled, and what limitations they have. https://docs.python.org/3/tutorial/floatingpoint.html is a Python specific explanation. In your particular example, Python chooses to use a representation that has a limited number of digits (depends on the Python version). Internally, different float values may share the...

Simplest Way of Rounding Up the Average in C++
First of all, make c a double, then use c = (a + b)/2.0 otherwise you have truncation due to division of ints being casted to int. In this way, (a + b) / 2.0 is a double, due to the denominator being a double, so you don't have any...

Operator / is type-specific, so you should cast your integer to the float, like this: ROUND(CAST(($Var3) AS float) / 6000), 2) or use the division by float, like this: ROUND(($Var3 / 6000.0), 2) Returns the data type of the argument with the higher precedence. For more information, see Data Type...

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...

RegEx Let's start with your RegEx. What you have will match decimal numbers with any number of decimal places, but also other things. ^((?:\d+(?:\.\d*)?)|(?:\.\d+))$ Explanation First of all we declare that if there is only an integer without decimal places, that's fine. However, we also allow the short hand .8...

PHP: number_format rounding
Not the rounding makes it -0. The $round variable contains this before the last line: string(3) "0.0" You can verify this with adding this line: var_dump($round); before the echo. So if you multiply "0.0" (string) with -1 then the result will be "-0" Because (string)0 is casted to (float)0 before...
Imitate Math.Round for GnuMP library in C#
Today I found an mathematically correct answer: public static Real Round(Real r, int precision) { Real scaled = Real.Pow(10, precision + 1); Real multiplied = r*scaled; Real truncated = Trunc(multiplied); Real lastNumber = truncated - Trunc(truncated/10)*10; if (lastNumber >= 5) { truncated += 10; } truncated = Trunc(truncated/10); return truncated...

eX is a valid part of a Number literal and means *10^X, just like in scientific notation: > 1e1 // 1 * Math.pow(10, 1) 10 > 1e2 // 1 * Math.pow(10, 2) 100 And because of that, converting a string containing such a character sequence results in a valid number:...
