Is this a bug? Thanks. It's counterintuitive but (float)7.2 => 7.199999809265136719e+00 in the machine representation, whereas (double)7.2 => 7.200000000000000178e+00, so the behavior is correct, i.e. (float)7.2 < (double)7.2. Generally float(x) != double(x) since there's a loss of information going from double to float, so the mapping can't be inverted. You can cast it, or write "test >= 7.2f", or store the variable as a double instead of float. -- Brian Gough Network Theory Ltd, Publishing "An Introduction to GCC" --- http://www.network-theory.co.uk/
