I prepared a test containing this:
str = @"1 1 1";
scanner = [[NSScanner alloc] initWithString: str];
[scanner scanDouble: &r];
[scanner scanDouble: &g];
[scanner scanDouble: &b];
isAtEnd = [scanner isAtEnd];
NSLog(@"parsed: %lf, %lf, %lf - isAtEnd? %d", r, g, b, isAtEnd);
[scanner release];
str = @"0 0 0";
scanner = [[NSScanner alloc] initWithString: str];
[scanner scanDouble: &r];
[scanner scanDouble: &g];
[scanner scanDouble: &b];
isAtEnd = [scanner isAtEnd];
NSLog(@"parsed: %lf, %lf, %lf - isAtEnd? %d", r, g, b, isAtEnd);
[scanner release];
does this look reasonable? it looks to me.
On intel I get an unexpected result:
2021-01-21 14:09:20.967 ScannerTest[26541:26541] parsed: 1.000000,
1.000000, 1.000000 - isAtEnd? 1
2021-01-21 14:09:20.968 ScannerTest[26541:26541] parsed: 1.000000,
1.000000, 1.000000 - isAtEnd? 1
which is consistent with SPARC:
2021-01-21 16:02:32.466 ScannerTest[5278:3930190648] parsed: 1.000000,
1.000000, 1.000000 - isAtEnd? 1
2021-01-21 16:02:32.555 ScannerTest[5278:3930190648] parsed: 1.000000,
1.000000, 1.000000 - isAtEnd? 1
but why not 0.0 the second time?
