My Finished 11.2 Class Implementation

[Qpido]

I decided to use what we've learned so far and make this scenario:

Code: (Objective-C)

#import "Fraction+Comparison.h"

@implementation Fraction (Comparison)

-(BOOL) isEqualTo:(Fraction *) f
{
    [self reduce];
    [f reduce];
    
    if ( self.numerator == f.numerator && self.denominator == f.denominator)
        return YES;
    else {
        return NO;
    }
}

-(int) compare: (Fraction *) f
{
    [self reduce];
    [f reduce];
    
    if ( (double)self.numerator / self.denominator > (double) f.numerator / f.denominator)
        return -1;
    else if ( [self isEqualTo:f] == YES)
        return 0;
    else {
        return 1;
    }
}

@end

Hope you enjoy!
