Can someone help me out that to finalize my help? Thank you. The s...
In php, we have number_format(). Passing it a value such as: number_format(3.00 * 0.175, 2); returns 0.53, which is what I would expect. However, in JavaScript using toFixed() var num = 3.00 * 0.175; num.toFixed(2); returns 0.52. Ok, so perhaps toFixed is not what I want... Maybe something like this... var num = 3.17 * 0.175; v...
Is it possible to round a decimals to the nearest .5 with PHP like this: number | round ---------------- 1.29 | 1.50 2.03 | 2.00 1.43 | 1.50 1.13 | 1.00 11.38 | 11.50 I tried with: $rnd= round($number,2); but I get decimals like the one in the column "number" above. ...
I have been using Math.Round(myNumber, MidpointRounding.ToEven) in c# to do my server-side rounding, however, the user needs to know 'live' what the result of the server-side operation will be which means (avoiding an ajax request) creating a javascript method to replicate the MidpointRounding.ToEven method used by c#. MidpointRounding....
Lets say I have a value of 3.4679 and want 3.46, how can I truncate to two decimal places that without rounding up? I have tried the following but all three give me 3.47: void Main() { Console.Write(Math.Round(3.4679, 2,MidpointRounding.ToEven)); Console.Write(Math.Round(3.4679, 2,MidpointRounding.AwayFromZero)); Console.Wr...
Say I have an array of integers: arr = [0,5,7,8,11,16] and I have another integer: n = 6 I need a function that rounds down to the nearest number from the array: foo(n) #=> 5 As you can see, the numbers do not have a fixed pattern. What's an elegant way to do this? Thanks ...
# max_list = [83, 1350, 1, 100] for i in range(len(max_list)): new_value = 1 while new_value < max_list[i]: new_value *= 10 max_list = new_value What I'm doing is rounding numbers up to the closest, uhm, zero filled value? I'm not sure what it would be called. But basically, I want 83 -> 100, 1 -> 1, 1350 -> 10...

Consider the following program: $x=12345678901.234567000; $y=($x-int($x))*1000000000; printf("%f:%f\n",$x,$y); Here's what is prints: 12345678901.234568:234567642.211914 I was expecting: 12345678901.234567:234567000 This appears to be some sort of rounding issue in Perl. How could I change it to get 234567000 instead? Did I do som...
I am writing a piece of code in which i have to convert from double to float values. I am using boost::numeric_cast to do this conversion which will alert me of any overflow/underflow. However i am also interested in knowing if that conversion resulted in some precision loss or not. For example double source = 1988.1012; floa...

Is there a way to round to the nearest number in the Boost library? I mean any number, 2's, 5's, 17's and so on and so forth. Or is there another way to do it? ...
Thoughout our app we use number_to_currency(value, :precision => 2). However, we now have a requirement whereby the value may need displaying to three or more decimal places, e.g. 0.01 => "0.01" 10 => "10.00" 0.005 => "0.005" In our current implementation, the third example renders as: 0.005 => "0.01" What's the best approach ...

All, Is there any in built function in java to tell me how many decimal places in a double. For example: 101.13 = 2 101.130 = 3 1.100 = 3 1.1 = 1 -3.2322 = 4 etc I am happy to convert to another type first if needed, I have looked at converting to bigdecimal first with no luck. Any help would be appreciated. Cheers, Karl ...
Hi, It started quite normally. I'm writing complex calculation application for iPhone. I decided to use float primitive for representing numbers.
