number-formatting

When I do the following: alert((2053716830872415770228778006271971120334843128349550587141047275840274143041).toString()); I get the "2.053716830872415e+75" exponential notation. I want to alert the number as is. I tried toFixed(), toPrecision() and toLocaleString() and they output the same thing. How can I accomplish this? Note: the number is a variable, so I cannot alert("208.."); Javascript uses 64-bit floating point numbers . It is impossible to precisely store your value in a Javascript number. Instead, you should use a BigInteger library. http://www.leemon.com/crypto/BigInt.html http:/

I have a JFormattedTextField with a NumberFormat with Locale.US. So the decimal separator is the point and the grouping separator is the comma. Now I type the string "1,23" in this text field and move the focus to another component. I would expect the string to disappear (like it does when i type "a" instead of "1,23") because it is obviously not a valid representation of a number when using Locale.US. But instead the text in the text field is changed to "123". This is because the used NumberFormat is not strict when parsing and simply ignores the comma. Question : How can I tell NumberFormat

I realise that in the states large numbers are formatted with a , between thousands so you would write $1,000,000.00 . In South Africa a , is non-standard and could be used as a decimal point instead of the . . We would write $1000000.00 which is horrible to read. The typical solution is to use a bit of whitespace: $1 000 000.00 . The problem with that solution is that it still looks terrible. If I assume values are currency formatted in a particular DOM element (i.e. the numbers are suffixed with .00 even if it's double zero), the ideal solution would be to use CSS to somehow manipulate the

Data for my Y axis (each country) has figures in millions: { date: "1960", germany: "72542990", spain: "30327000", france: "46621166", italy: "50025500" } How do I write the .tickFormat(d3.format("")); on my Y axis variable to format the tick values so they show up in the Y axis scale like this: 0, 20 million, 40 million, 60 million, 80 million Currently they show up as 0, 20000000, 40000000, 60000000,80000000 Thanks. Declare Formatter formatValue = d3.format(".2s"); Use inside TickFormat .tickFormat(function(d) { return formatValue(d)}); to replace M with million try this.. .tickFormat

The question is pretty self-explanatory, I suppose. I am using printf and friends (snprintf etc) to display some memory statistics that are in the millions or hundreds-of-thousands range. Reading a number formatted like "1,523,556" is much easier than "1523556" to my lazy way of thinking. I have tried setting the locale and using the apostrophe flag before the format specifier (%'d and %'llu), but the apostrophe is apparently a standard from the SUS, so it may not work for me under Windows anyway. Is there a Windows-specific API for doing this? I am working with Pelles C and programming in
