vec_ctiwu

Purpose

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

Syntax

d=vec_ctiwu(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 2³²-1, the result is maximal unsigned integer (0xFFFF FFFF).
If the rounded value is less than 0, the result is 0 (0x0000 0000).
Otherwise, the result is the 32-bit unsigned integer value equivalent to the rounded value.

Example

FPSCR_RN = DFP_ROUND_TOWARD_POSITIVE_INFINITY
a =  (1.4, 1.9,      9.0e11, -5.0e12)
d: (  2,   2, 0xFFFF FFFF,       0)
