div GPU Virtual ISA NVIDIA

Divide Arithmetic

div.stype d, a, b;

Divide the first operand by the second.

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.

Syntax Forms

One mnemonic covers many type / state-space / scope / modifier combinations — each row below is an independently valid form.

Syntax Data Types State Space(s) Modifiers Min. Target Description
div.stype d, a, b; s32, s64, u32, u64 sm_10 Integer division.
div.approx.f32 d, a, b; f32 approx sm_10 Fast approximate single-precision division.
div.rn.f64 d, a, b; f64 rn sm_10 IEEE-754 round-to-nearest double-precision division.

Operands

  • d
    Destination register
