Unfortunately, hardly many bookmakers now provide profitable wagers on cybersports. I have been playing on loki casino mobile for a very long time. I would strongly advise checking at the URL I provided above if you're seeking for a reputable bookmaker with a big selection of well-liked games.

I think for this special libraries should be used, like winapi (maybe GetCurrencyFormatW ) or gnu gettext.

The API is indeed a bit "English-centric". The documentation for [strutils.formatFloat()](https://nim-lang.org/docs/strutils.html#formatFloat%2Cfloat%2CFloatFormatMode%2Crange%5B%5D%2Cchar) allows the user to specify the separator between the integer and rational part of a number via the `decima

The proposed API feels too English-centric. For example, how would you produce numbers in Indian format (12,34,56,789.0)?

I like it; would you consider writing a PR? there's a few things I would change in the API but it could be addressed in code review. also, this case fails: doAssert fmtFloat(-0.0, 1, "t") == "-0.0" Run you can use math.signbit, or better, factor out the 1st part wi

I do this: import math import strformat # -- proc fmtFloat*(value: float, decimals: int, format: string = ""): string = if value != value:

see previous attempt here: I still think this would be a useful API, but a new proposal should use the discussions in that PR into account.

Be very careful with this because different languages format numbers in different ways. If your project is meant to be international, you'll have to use a library.

Thanks! I was sure someone else had this problem before. I'll try it out.

Formatting a float to currency

`insertSep` from module `strutils` is able to insert separators, but it doesn’t work well with floats: import strutils echo ($12345.67).insertSep(',')# 12,345,.67. Run So we have to do some work to get the right result: import strutils var s =

Formatting a float to currency

I want to format a float, e.g. 12345.67 to a string as if it were a currency, e.g. "12,345.67". Is there a standard way of doing this with Nim?
