#!N  #!Rdxef DXExtractFloat #!N #!N Function #!N #!N Determines whether an 
Object can be converted to a floating-point value, and if so, 
extracts it. #!N #!N Syntax #!N  #!F-adobe-times-bold-r-normal--18*   #include <dx/dx.h> Object DXExtractFloat(Object 
o, float *fp) #!EF #!N #!N Functional Details #!N #!N If 
Object  #!F-adobe-times-bold-r-normal--18*   o #!EF can be converted to a floating-point value 
(i.e.,  #!F-adobe-times-bold-r-normal--18*   TYPE_FLOAT #!EF ,  #!F-adobe-times-bold-r-normal--18*   CATEGORY_REAL #!EF , rank 0), 
this routine extracts it and places it in  #!F-adobe-times-bold-r-normal--18*   *fp #!EF 
. #!N #!N Return Value #!N #!N Returns  #!F-adobe-times-bold-r-normal--18*   o #!EF 
and sets  #!F-adobe-times-bold-r-normal--18*   *fp #!EF if a floating-point value can be 
extracted from  #!F-adobe-times-bold-r-normal--18*   o #!EF ; otherwise, returns  #!F-adobe-times-bold-r-normal--18*   NULL #!EF
