Function
Determines whether an Object can be converted to a floating-point value, and if so, extracts it.
Syntax
#include <dx/dx.h>
Object DXExtractFloat(Object o, float *fp)
Functional Details
If Object o can be converted to a floating-point value (i.e., TYPE_FLOAT, CATEGORY_REAL, rank 0), this routine extracts it and places it in *fp.
Return Value
Returns o and sets *fp if a floating-point value can be extracted from o; otherwise, returns NULL without setting an error code.
