vec_ctiw

Purpose

Converts a quad vector to 32-bit signed integer values.

Syntax

d=vec_ctiw(a)

Result and argument types

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

d	a
`vector4double`	`vector4double`

Result value

Each element of a is rounded to floating-point integral value according to FPSCR_RN. 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.

Example

FPSCR_RN = DFP_ROUND_TOWARD_POSITIVE_INFINITY
a =  (1.4, -2.9,      9.0e11,     -5.0e12)
d: (  2,   -2, 0x7FFF FFFF, 0x8000 0000)
