vec_ctiwz

Purpose

Converts a quad vector to 32-bit signed integer values with rounding toward zero.

Syntax

d=vec_ctiwz(a)

Result and argument types

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

Result value

Each element of a is rounded towards zero to floating-point integral value. The four low-order bytes of the corresponding element of the result vector then contain one of the following values:

• If the rounded value is greater than 2³¹-1, the result is maximal integer (0x7FFF FFFF).
• If the rounded value is less than -2³¹, the result is minimal integer (0x8000 0000).
• Otherwise, the result is the 32-bit signed integer value equivalent to the rounded value.
