iPhone NSNumberFormatter for less than 1 value

I have a floating point value

i.e. 0.0467

Want have a string 05 how can get it? Excluding the decimal point (.).

More precisely, if I have a floating point num开发者_如何学Cber, I want to divide it to integral and decimal, preferably into two string parts.

By following this, you will get desired result.

    float floatValue = 0.0467;
    NSString *str = [NSString stringWithFormat:@"%.2f", floatValue];
    str = [str stringByReplacingCharactersInRange:NSMakeRange(0, 2) withString:@""];
    NSLog(@"%@", str);    // Result will be: 05

fDecimal = 0.04567;
NSString * strDecimal = [NSString stringWithFormat:@"%0.2f", fDecimal];
NSString * strDecimalPart = [strDecimal substringWithRange:NSMakeRange(2, 2)];

The setting you are looking for is called fraction digits:

NSNumberFormatter* f = [[[NSNumberFormatter alloc] init] autorelease;
[f setMaximumFractionDigits:2];

Optionally you can use -[NSNumberFormatter setRoundingMode:] to specify how rounding should be done.
