Integer
DIM Var AS Integer
This native datatype represents an Integer value, i.e. a four byte signed integer value.
The value of an Integer is between -2147483648 and +2147483647. (-2^31 and 2^31-1) For larger integers, use
Long.
Integer values can be written in decimal, hexadecimal, octal, or binary:
-
Hexadecimal values start with
&, &H or &h.
-
Binary values start with
%, &X or &x.
-
Octal values start with
&O or &o.
For a bad reason of compatibility with Visual Basic™, four-digits hexadecimal constants are sign expanded from bit 15 to bits 16 up to 31
if no trailing
& is added to the constant.
Consider this when defining colors as constants :
&HFF00 will be fully transparent yellow,
because it will be sign expanded to
&HFFFFFF00, whereas
&HFF00& will be green.
