Fvec Notation Conventions

Fvec Classes Syntax Notation

Fvec classes use the syntax conventions shown the following examples:

[Fvec_Class] R = [Fvec_Class] A [operator][Ivec_Class] B;

Example 1: F64vec2 R = F64vec2 A & F64vec2 B;

[Fvec_Class] R = [operator]([Fvec_Class] A,[Fvec_Class] B);

Example 2: F64vec2 R = andnot(F64vec2 A, F64vec2 B);

[Fvec_Class] R [operator]= [Fvec_Class] A;

Example 3: F64vec2 R &= F64vec2 A;

where

[operator] is an operator (for example, &, |, or ^ )

[Fvec_Class] is any Fvec class ( F64vec2, F32vec4, or F32vec1 )

R, A, B are declared Fvec variables of the type indicated.

Return Value Notation

Because the Fvec classes have packed elements, the return values typically follow the conventions presented in the Return Value Convention Notation Mappings table. F32vec4 returns four single-precision, floating-point values (R0, R1, R2, and R3); F64vec2 returns two double-precision, floating-point values, and F32vec1 returns the lowest single-precision floating-point value (R0).
