Expert Solution
Step 1 rule to conversion
I convert a double to scientific notation
Add std::fixed to stream i.e.
// Set Fixed -Point Notation
streamObj2 << std::fixed;
It will force the c++ to convert double using fixed-point notation instead of scientific one. For example,
// Create an output string stream
std::c++ streamObj2;
// Set Fixed -Point Notation
streamObj2 << std::fixed;
//Add double to stream
streamObj2 << num;
// Get string from output string stream
std::string strObj2 = streamObj2.str();
