[question] Porting from boost multiprecision #234
Description
Hi,
I'm thinking on creating a branch to move away from boost in Triton. I have multiple questions:
- Casting one type to another should be as easy to use
static_cast<T>(value)right? i.e.
this->memory[addr+i] = (cv & 0xff).convert_to<triton::uint8>(); // old
this->memory[addr+i] = static_cast<triton::uint8>((cv & 0xff)); //new- How can I cast a number to string? Is the following correct?
math::wide_integer::uint512_t value = <whatever>;
std::stringstream ss;
ss << value;
std::string strValue(ss.str());- How can I cast from a
std::stringto amath::wide_integer::uint512_t? - How can I create a wide integer whose size is 80 bits? This is the code I want to replicate. I've tried the follwing:
typedef math::wide_integer::uintwide_t<static_cast<size_t>(UINT32_C(80)), std::uint32_t> uint80;but I get:
error C2338: Error: Width2 must be 2^n times 1...63 (with n >= 3), while being 16, 24, 32 or larger, and exactly divisible by limb count
because of:
// Verify that the Width2 template parameter (mirrored with my_width2):
// * Is equal to 2^n times 1...63.
// * And that there are at least 16, 24 or 32 binary digits, or more.
// * And that the number of binary digits is an exact multiple of the number of limbs.
static_assert( (detail::verify_power_of_two_times_granularity_one_sixty_fourth<my_width2>::conditional_value)
&& (my_width2 >= 16U) // NOLINT(cppcoreguidelines-avoid-magic-numbers,readability-magic-numbers)
&& (my_width2 == (number_of_limbs * static_cast<size_t>(std::numeric_limits<limb_type>::digits))),
"Error: Width2 must be 2^n times 1...63 (with n >= 3), while being 16, 24, 32 or larger, and exactly divisible by limb count");
Thank you so much for your help
