Bug ID: 114862
Summary: std::uppercase not applying to nan's and inf's
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: lcarreon at bigpond dot net.au
Target Milestone: ---
The following code:
#include <limits>
#include <iostream>
#include <iomanip>
int main()
{
double values[] =
{
std::numeric_limits<double>::quiet_NaN(),
-std::numeric_limits<double>::quiet_NaN(),
std::numeric_limits<double>::signaling_NaN(),
-std::numeric_limits<double>::signaling_NaN(),
std::numeric_limits<double>::infinity(),
-std::numeric_limits<double>::infinity()
};
for (const auto& value : values)
{
std::cout
<< std::uppercase
<< std::fixed << std::setw(17) << std::left << value
<< " "
<< std::fixed << std::setw(10) << std::left << std::setprecision(0) <<
value
<< " "
<< std::fixed << std::setw(15) << std::left << std::setprecision(4) <<
value
<< " "
<< std::fixed << std::setw(17) << std::left << std::setprecision(6) <<
value
<< std::endl;
}
return 0;
}
Generates the following output:
nan nan nan nan
-nan -nan -nan -nan
nan nan nan nan
-nan -nan -nan -nan
inf inf inf inf
-inf -inf -inf -inf
Which in my opinion is incorrect because it is not applying std::uppercase.
