Re^4: problem with variables

Actually, now that brain is in gear, I think you *always* want to use eq rather than == for comparing floats. If you use

sprintf( "%.3f", $num1 ) == sprintf( "%.3f", $num2 )

that just puts you right back to where you started: comparing floats with ==.

Yes, but if the strings are eq, the floats that come from those strings will be ==. It's a deterministic thing. That said, it makes more sense to compare them with eq, since the output of sprintf is a string. Why force the conversion back? Caution: Contents may have been coded under pressure.	[reply]
