cos GPU Virtual ISA NVIDIA

cos Floating-Point Instructions

cos.approx{.ftz}.f32 d, a;

Find the cosine of the angle a (in radians).

Encoding

PTX is a virtual instruction set. It has no single, stable native binary encoding - the compiler lowers this instruction to different native machine code depending on the selected NVIDIA target architecture (compute capability). This page intentionally shows no bit-diagram; see the target/version requirements below for what governs how this instruction compiles.
