vec_trunc: Vector Truncate

d = vec_trunc(a)

Returns a vector containing the truncated values of the corresponding elements of the given vector. Each element of the result contains the value of the corresponding element of a, truncated to an integral value.

Note: vec_trunc provides the same functionality as vec_roundz, except that vec_trunc could trigger the IEEE-inexact exception.

Table 1. Vector Truncate
d	a	MIN ARCH
vector float	vector float	ARCH(12) 2
vector double	vector double	ARCH(11) 2
Note: 2. This prototype has slightly different semantics than that in the OpenPOWER ABI for Linux® Supplement for the Power Architecture® 64-bit ELF V2 ABI, Revision 1.4. In z/OS® XL C/C++, `vec_trunc` could trigger the IEEE-inexact exception.
