Original PTX specification:
div.type d, a, b; .type = { .u16, .u32, .u64, .s16, .s32, .s64 };
div.approx{.ftz}.f32 d, a, b; // fast, approximate divide div.full{.ftz}.f32 d, a, b; // full-range approximate divide div.rnd{.ftz}.f32 d, a, b; // IEEE 754 compliant rounding div.rnd.f64 d, a, b; // IEEE 754 compliant rounding .rnd = { .rn, .rz, .rm, .rp };
