number-formatting

I'm working on an international project and have observed that, in Java, the choice of the decimal separator is based on the Locale's language, not its country. For example: DecimalFormat currencyFormatter = (DecimalFormat) NumberFormat.getInstance(new Locale("it","IT")); System.out.println(currencyFormatter.format(-123456.78)); currencyFormatter = (DecimalFormat) NumberFormat.getInstance(new Locale("en","IT")); System.out.println(currencyFormatter.format(-123456.78)); produces the following output: -123.456,78 -123,456.78 I would have expected it to follow the country, since if I'm in the

What is the easiest way to pad a string with 0 to the left so that "110" = "00000110" "11110000" = "11110000" I have tried to use the format! macro but it only pads to the right with space: format!("{:08}", string); Shepmaster The fmt module documentation describes all the formatting options: Fill / Alignment The fill character is provided normally in conjunction with the width parameter. This indicates that if the value being formatted is smaller than width some extra characters will be printed around it. The extra characters are specified by fill , and the alignment can be one of the

I see that, in C#, rounding a decimal , by default, uses MidpointRounding.ToEven . This is expected, and is what the C# spec dictates. However, given the following: A decimal dVal A format string sFmt that, when passed in to dVal.ToString(sFmt) , will result in a string containing a rounded version of dVal ...it is apparent that decimal.ToString(string) returns a value rounded using MidpointRounding.AwayFromZero . This would appear to be a direct contradiction of the C# spec. My question is this: is there a good reason this is the case? Or is this just an inconsistency in the language? Below,

How do you set the vertical axis to display percent such as 25%, 50%, 75%, 100%? jroi_web var options = { title: 'Chart Title', vAxis: { minValue: 0, maxValue: 100, format: '#\'%\'' } }; Try escaping the % sign. I've used this to just append the % sign in the y axis. chart.draw(data, {vAxis: {format:'#%'} } ); To get comma for thousands, use {format:'#,###%'} . See http://code.google.com/apis/chart/interactive/docs/gallery/linechart.html Using bar charts, I found my results haphazard and I got to consistency by doing the following: 1. In your data column, set a value of 100, even if you add a
