Description

Procedures that perform a certain function with their operands. They do the same actions that the native FreeBasic operators but with variants. For detailed descriptions see the FreeBasic documentation.

Global Operators

Cast Operators

Assignment operators

Arithmetic operators

Relational operators

Bitwise operators

Using the pointer syntax: Using the constructors

Remarks

I haven't added a cast to return a numeric value because with procedures like PRINT that can use both a number or a string the compiler will fail, not knowing which cast it should use. If you want to convert it to a number, use VAL(DVARIANT).

Examples

SUB Foo (BYVAL v AS VARIANT) PRINT AfxVarToStr(@v) END SUB DIM dv AS DVARIANT = "Test string" Foo dv

SUB Foo (BYVAL v AS VARIANT) PRINT AfxVarToStr(@v) END SUB DIM pdv AS DVARIANT PTR = NEW DVARIANT("Test string") Foo *pdv Delete pdv

SUB Foo (BYVAL v AS VARIANT) PRINT AfxVarToStr(@v) END SUB Foo DVARIANT(12345, "LONG")

SUB Foo (BYREF v AS VARIANT) PRINT AfxVarToStr(@v) END SUB Foo DVARIANT(12345, "LONG")

SUB Foo2 (BYVAL v AS VARIANT) PRINT AfxVarToStr(@v) END SUB Foo2 DVARIANT(12345, "LONG")

SUB Foo3 (BYREF dv AS DVARIANT) PRINT dv END SUB Foo3 DVARIANT(12345, "LONG")

SUB Foo4 (BYVAL dv AS DVARIANT PTR) PRINT AfxDVarToStr(dv) END SUB Foo4 @DVARIANT(12345, "LONG")
