		sivachandraUnsubmitted Done Reply Inline Actions Using `fputil:UInt` is probably an overkill here if all you want is a 128-bit integer. You should probably use `__uint128_t`. For the access to the individual 32-bits words, you can use a `MutableArrayRef`: https://github.com/llvm/llvm-project/blob/main/libc/utils/CPP/ArrayRef.h#L123. So, something like this: __uint128_t finalApprox = mantissa; MutableArrayRef<uint32_t> finalApproxWords(reinterpret_cast<uint32_t >(&finalApprox, 4); To reduce verbosity, you can may be define: using UInt128Words = MutableArrayRef<uint32_t>; static inline UInt128Words makeUInt128Words(__uint128_t val) { return UInt128Words(reinterpret_cast<uint32_t >(val), 4); } That said, I will leave it up to you to decide which is more readable. sivachandra:* Using `fputil:UInt` is probably an overkill here if all you want is a 128-bit integer.
