Aright, what’s up with this? This code using a double works just fine:
|
1 2 3 4 5 6 7 8 9 |
double myDouble = 2.2;
NSLog(@"myDouble %f", myDouble);
[self testDouble:myDouble];
- (void) testDouble:(double)myDouble {
NSLog(@"testDouble %f", myDouble);
} |
This code prints: myDouble 2.200000 testDouble 2.200000 No surprises there. But the same code using a float behaves very strangely:
|
1 2 3 4 5 6 7 8 9 |
float myFloat = 3.3;
NSLog(@"myFloat %f", myFloat);
[self testFloat:myFloat];
- (void) testFloat:(float)myFloat {
NSLog(@"testFloat %f", myFloat);
} |
This code prints myFloat 3.300000 testFloat 36893488147419103232.000000 So what happens to the float that is passed to the testFloat method? [...]
