>Using VFP 5.0, we are calling a function in a DLL that we wrote. The function in C++ returns a float. We have tried to declare it as first SINGLE and the DOUBLE. In both cases, the function was called, it returned a floating point number (checked from the debugger). It both cases, the return value was truncated to an integer. Does anyone have an idea what I'm not doing correctly?
