Bug in [NSScanner scanDouble:]

[Douglas Simons]

Hi, sorry for posting a bug report here, but I seem to have lost my credentials for accessing the bug tracker.

The scanDouble: method of NSScanner is adding a tiny fraction to the value scanned (at least on Windows).

NSScanner *scanner = [NSScanner scannerWithString:@“197319600.000000”];

double val = 0.0;

[scanner scanDouble:&val];

NSLog(@"scanDouble got: %.9f", val);

// results in val having the value 197319600.00000012

Note that NSString’s doubleValue method doesn’t have this problem, so I’m using that to work around this problem for now.

Thanks!

Doug
