The … Read more
How to properly format currency on ios
You probably want something like this (assuming currency is a float): NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle]; NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat:currency]]; From your requirements to treat 52 as .52 you may need to divide by 100.0. The nice thing about this approach is that it will respect the current locale. … Read more
Is there a way to round numbers into a reader friendly format? (e.g. $1.1k) [closed]
Here is a simple function to do it: function abbrNum(number, decPlaces) { // 2 decimal places => 100, 3 => 1000, etc decPlaces = Math.pow(10,decPlaces); // Enumerate number abbreviations var abbrev = [ “k”, “m”, “b”, “t” ]; // Go through the array backwards, so we do the largest first for (var i=abbrev.length-1; i>=0; i–) … Read more

Rounding integers to nearest multiple of 10 [duplicate]
I would just create a couple methods; int RoundUp(int toRound) { if (toRound % 10 == 0) return toRound; return (10 – toRound % 10) + toRound; } int RoundDown(int toRound) { return toRound – toRound % 10; } Modulus gives us the remainder, in the case of rounding up 10 – r takes you … Read more
