vec_sub
Purpose
Returns a vector containing
the result of subtracting each element of b
from the corresponding element of a
.
This function emulates the operation on long long vectors.
Syntax
d=vec_sub(a, b)
Result and argument types
The following table describes the types of the returned value and the function arguments.
d | a | b |
---|---|---|
The same type as argument a |
vector signed char | The same type as argument a |
vector unsigned char | ||
vector signed short | ||
vector unsigned short | ||
vector signed int | ||
vector unsigned int | ||
vector signed long long | ||
vector unsigned long long | ||
vector float | ||

Result value
The value of each element of
the result is the result of subtracting the value of the corresponding
element of b
from
the value of the corresponding element of a
. The arithmetic
is modular for integer vectors.
