Example 2:

Explicit conversion can also be used when you are sure which type you want to

convert expression to. Consider the following lines:

dim tA as byte

dim tB as byte

dim tC as byte

dim A_ as short

dim B_ as short

tA = byte(A_)

B_ = short(tA + tB * tC)

It is important to understand that explicit conversion between signed and unsigned

data does not change binary representation of data; it only allows copying source

to destination. Thus, if A_ was -1, its binary representation would be 11111111,

and A would become 255.

Even if you have ordered the explicit conversion, compiler will perform implicit if

necessary.

Example 3:

You cannot execute explicit conversion on the operand left of the assignment oper-

ator:

word(b) = Bb

' compiler will report an error.
