The values that the function returns are converted to one of the function's types. The possible value types are converted as shown in the following table:

Function return type	Result
`char, short`	Sign extended to long integer
`byte, word`	Promoted to long integer without sign extension
`long, dword`	Unchanged
`float`	Promoted to double-precision floating point value
`double`	Unchanged
`pointer`	Cast to long integer
`string`	String
