NSNumber floatValue not equal to NSNumber value
- by Mirkules
Hi Everyone,
First post here. Having a problem with NSNumber's floatValue method -- somehow, it returns an imprecise number. Here's the problem: I store a bunch of NSNumbers in an array, like this:
NSArray *a = [NSArray arrayWithObjects:
[NSNumber numberWithFloat:0.04f],
[NSNumber numberWithFloat:0.028f],
[NSNumber numberWithFloat:0.016f],
[NSNumber numberWithFloat:0.004f],
nil];
Then I try to retrieve the first value (for example):
NSNumber n = (NSNumber) [a objectAtIndex:0];
CGFloat f = [n floatValue];
In the debugger, n shows a value of 0.04 (in the summary column), but f shows a value of 0.0399999991. What am I doing wrong here?
Thanks everyone.
