vec_swdiv, vec_swdiv_nochk

Purpose

Returns a vector containing the result of dividing each element of a by the corresponding element of b.

Syntax

d=vec_swdiv(a, b)
d=vec_swdiv_nochk(a, b)

Result and argument types

The following table describes the types of the returned value and the function arguments.

d	a	b
`vector4double`	`vector4double`	`vector4double`

For vec_swdiv_nochk, the compiler does not check the validity of the arguments. You must ensure that the following conditions are satisfied where x represents each element of a and y represents the corresponding element of b:

2^-1021 ≤ |y| ≤ 2¹⁰²⁰
If x ≠ 0.0
- 2^-969 ≤ |x| < Infinity
- 2^-1020≤ |x / y| ≤ 2¹⁰²²

Result value

The values of the elements of the result are obtained by dividing the elements of a by the corresponding elements of b.

When the following options are used, the result is bitwise identical to the IEEE division.

-qstrict=precision
-qstrict=ieeefp
-qstrict=zerosigns
-qstrict=operationprecision

Otherwise, the result might differ slightly from the IEEE division.

Formula

d[0] = a[0] / b[0]
d[1] = a[1] / b[1]
d[2] = a[2] / b[2]
d[3] = a[3] / b[3]

Example

a =  (50.0,  1.0,  30.0,  40.0)
b =  (10.0,  5.0,  -1.0,  80.0)
d: ( 5.0,  0.2, -30.0,   0.5)
