DXExtractFloat

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
