Be careful when using stringByTrimmingCharactersInSet as it will trim from _both_ ends of the receiver.

The string 0.0050 will become 005

While I don't have time to do exhaustive testing, doing a "round-trip" conversion seems to do what you want:

- (NSString*)stringWithFormattedFloat:(float)aValue
{
	NSString*	theString = [NSString stringWithFormat:@"%0.4f", aValue];
	
	NSLog (@"intermediate string %@", theString);
	
	return [NSString stringWithFormat:@"%g", [theString floatValue]];
}

- (void)applicationDidFinishLaunching:(NSNotification*)aNotification
{
	NSLog (@"final string %@", [self stringWithFormattedFloat:0]);
	NSLog (@"final string %@", [self stringWithFormattedFloat:0.987654]);
	NSLog (@"final string %@", [self stringWithFormattedFloat:0.5]);
}


Here's the test run output:

2004-12-30 17:43:30.862 trim[7854] intermediate string 0.0000
2004-12-30 17:43:30.863 trim[7854] final string 0
2004-12-30 17:43:30.863 trim[7854] intermediate string 0.9877
2004-12-30 17:43:30.863 trim[7854] final string 0.9877
2004-12-30 17:43:30.863 trim[7854] intermediate string 0.5000
2004-12-30 17:43:30.863 trim[7854] final string 0.5
