Hi,
why does the following code not compile?
---8<---
#include <iostream>
#include
#include
#include <algorithm>
#include <cmath>
int main()
{
using namespace ::boost::lambda;
const boost::array factor = {
1e12,
1e9,
1e6,
1e3,
1,
1e-3,
1e-6,
1e-9,
1e-12,
1e-15
};
boost::array values;
std::transform( factor.begin(), factor.end(),
values.begin(),
std::abs( ret<double>( 1e3 / _1 ) ) );
}
