How to trim zeros after decimal point

Question

I am trying to trim zeros after a decimal point as below but it\'s not giving desired result.

trig = [currentVal doubleValue];
trig = trig/100;
NSNumberForma         


        

Answer 1

This may not be a proper solution where there is NSNumberFormetter Class, But I just did this rather then googling a lot! ;)

Here is an example, if it helps:

-(NSString*) trimZerosAfterDecimalPoint:(NSString*)string_ {

    double doubleValue=[string_ doubleValue];    
    long   leftPart=(long)doubleValue;
    double rightPart=doubleValue-(double)leftPart;

    NSString *rightPartAsStr=[NSString stringWithFormat:@"%f", rightPart];

    int i=0;
    for (i=rightPartAsStr.length-1; i>=2; i--) {
        if ([rightPartAsStr characterAtIndex:i]!='0') {            
            rightPartAsStr=[rightPartAsStr substringWithRange:NSMakeRange(2, i-1)];
            break;
        }
    }

    if (i<2) {
        string_=[NSString stringWithFormat:@"%ld", leftPart];
    } else {
        string_=[NSString stringWithFormat:@"%ld.%@", leftPart, rightPartAsStr];
    }

    return string_;
}
