Hi, I don't know exactly when the change occurs (was it with gcc 4.1, 4.2, 4.3?), but I'm experiencing problems with the atof and strtof functions since then.
In one of my C++ projects, I'm using atof to recover data from an ASCII file to convert them into a float value. But, string s( "0.549" ); cerr << atof( s ) << endl; // Returns 0 cerr << atof( "0.513" ) << endl; // Returns 0 cerr << atof( "1.117" ) << endl; // Returns 1 I've tried to replace the calls to atof by calls to strtof. Same problem. By contrast, a single test project with only the above lines of code gives the expected results (i.e., 0.549, 0.513 and 1.117). So this may be due to incorrect cascaded headers. I have #include <cstdlib> however. I've also read this thread ( http://www.unix.com/high-level-programming/60607-interesting-implementation-atol-atof-etc.html), but unfortunately, I don't get any compiler error or warning, so this may be irrelevant. This is on a hp workstation zx6000 running up-to-date Debian Testing with gcc 4.3.1-2. I can't reproduce this problem on an x86 PC, unfortunately not running Debian, but with gcc 4.3.1 too. Any idea what's going wrong? Thank you for any input. Émeric
