I need to use the log() function so I've included float.h. Written the code. It compiles but I get a linker error.that the _DSFLOAT and so on are not found. I've checked off float=IEEE32 in the Code Generation line. Oddly though there's also a -D__NO_FLOAT__ in the command line. I can't find any check box to remove that. It doesn't matter that I remove it. I suspect I have to change my ansixbi.lib to one that handles floats.
1. Other than editing how do I remove the -D__NO_FLOAT__
2. How do I decide which library to use.
