#!N
#!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
without setting an error code. #!N #!N See Also #!N #!N
