vfp

Overview

vfp.h declares a set of floating-point arithmetic, transcendental and trigonometric functions, on 128-bit vectors, using the floating-point types from vecLibTypes.h.

These functions are named with their customary mathematical names, prefixed with the letter “v”, and all except vtablelookup() have the suffix “f” to indicate that they work with single-precision floating-point data. For example, vcosf is the single-precision cosine function.
