Output Operations

The two single, double-precision floating-point values of
A
are placed in the output buffer and printed in decimal format as follows:
cout << F64vec2 A;
"[1]:A1 [0]:A0"
Corresponding intrinsics: none
The four, single-precision floating-point values of
A
are placed in the output buffer and printed in decimal format as follows:
cout << F32vec4 A;
"[3]:A3 [2]:A2 [1]:A1 [0]:A0"
Corresponding intrinsics: none
The lowest, single-precision floating-point value of
A
is placed in the output buffer and printed.
cout << F32vec1 A;
Corresponding intrinsics: none

Element Access Operations

double d = F64vec2 A[int i]

Read one of the two, double-precision floating-point values of

A

without modifying the corresponding floating-point value. Permitted values of

i

are 0 and 1. For example:

double d = F64vec2 A[1]; 

If DEBUG is enabled and

i

is not one of the permitted values (0 or 1), a diagnostic message is printed and the program aborts. Corresponding intrinsics: none

float f = F32vec4 A[int i]

Read one of the four, single-precision floating-point values of

A

without modifying the corresponding floating point value. Permitted values of

i

are 0, 1, 2, and 3. For example:

float f = F32vec4 A[2]; 
		

If DEBUG is enabled and

i

is not one of the permitted values (0-3), a diagnostic message is printed and the program aborts.

Corresponding intrinsics: none

Element Assignment Operations

F64vec4 A[int i] = double d;

Modify one of the two, double-precision floating-point values of

A

. Permitted values of

int i

are 0 and 1. For example:

F32vec4 A[1] = double d;
F32vec4 A[int i] = float f;

Modify one of the four, single-precision floating-point values of
A
. Permitted values of
int i
are 0, 1, 2, and 3. For example:
F32vec4 A[3] = float f; 
		
If DEBUG is enabled and
int i
is not one of the permitted values (0-3), a diagnostic message is printed and the program aborts.
Corresponding intrinsics: none.
