Code: float f = 3.14159; char* buf = (char*)&f; var i; for (i = 0; i < sizeof(float); i ++) { file_asc_write(file, (var)(buf[i])); } reading works accordingly. i haven't tested it, so if it doesn't work try left-shifting the var by 10: Code: file_asc_write(file, (var)(buf[i]) << 10); Last edited by Joey; 06/20/08 13:37.
