vec_ctidu

Purpose

Converts a quad vector to 64-bit unsigned integer values.

Syntax

d=vec_ctidu(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 corresponding element of the result vector is then set to one of the following values:

If the rounded value is greater than 2⁶⁴-1, the result is maximal unsigned long integer (0xFFFF FFFF FFFF FFFF).
If the rounded value is less than 0, the result is 0 (0x0000 0000 0000 0000).
Otherwise, the result is the 64-bit unsigned integer value equivalent to the rounded value.

Example

FPSCR_RN = DFP_ROUND_TOWARD_POSITIVE_INFINITY
a =  (1.4, 1.9,                9.0e22, -5.0e25)
d: (  2,   2, 0xFFFF FFFF FFFF FFFF,       0)
