Hi,
how should i configure vs code to use Boost?
I tried to compile the following example:
#include <iostream>
#include
#include
int main()
{
using namespace boost::multiprecision;
// Operations at 128-bit precision and full numeric_limits support:
float128 b = 2;
// There are 113-bits of precision:
std::cout << std::numeric_limits<float128>::digits << std::endl;
// Or 34 decimal places:
std::cout << std::numeric_limits<float128>::digits10 << std::endl;
// We can use any C++ std lib function, lets print all the digits as well:
std::cout << std::setprecision(std::numeric_limits<float128>::max_digits10)
<< log(b) << std::endl; // print log(2) = 0.693147180559945309417232121458176575
// We can also use any function from Boost.Math:
std::cout << boost::math::tgamma(b) << std::endl;
// And since we have an extended exponent range we can generate some really large
// numbers here (4.02387260077093773543702433923004111e+2564):
std::cout << boost::math::tgamma(float128(1000)) << std::endl;
//
// We can declare constants using GCC or Intel's native types, and the Q suffix,
// these can be declared constexpr if required:
constexpr float128 pi = 3.1415926535897932384626433832795028841971693993751058Q;
return 0;
}
but that's what I get:
Executing task: g++-10 -g -std=c++17 '-fext-numeric-literals' main.cpp -L/usr/local/Cellar/gcc/10.2.0/lib/gcc/10/ -lquadmath -o main.out <
