Rules for Operators

To use operators with the
Ivec
classes you must use one of the following three syntax conventions:
[ Ivec_Class ] R = [ Ivec_Class ] A [ operator ][ Ivec_Class ] B
Example 1:
I64vec1 R = I64vec1 A & I64vec1 B;
[ Ivec_Class ] R =[ operator ] ([ Ivec_Class ] A,[ Ivec_Class ] B)
Example 2:
I64vec1 R = andnot(I64vec1 A, I64vec1 B);
[ Ivec_Class ] R [ operator ]= [ Ivec_Class ] A
Example 3:
I64vec1 R &= I64vec1 A;
[
operator
] represents an operator (for example, &, |, or ^ )
[
Ivec_Class
] represents an
Ivec
class
R
,
A
,
B
variables are declared using the pertinent
Ivec
classes
The table that follows shows automatic and explicit sign and size typecasting. "Explicit" means that it is illegal to mix different types without an explicit typecasting. "Automatic" means that you can mix types freely and the compiler will do the typecasting for you.
