The setprecision is a manipulator function in C++ which is used to sets the decimal precision of floating-point values on output operations. This setprecision is the built-in function defined in <iomanip> header file in C++. The decimal number could contain an infinite length number which require...

When used in an expressionout << setprecision(n)orin >> setprecision(n), sets the precision parameter of the stream out or in to exactly n. Parameter of this function is integer, which is new value for precision. Example: #include <iostream> ...
I am using the std::setprecisi on function to format variables of type double in a string however I am unsure how to stop this appearing in scientific notation. For example std::stringstre am buffer; buffer << setprecision(1) << 40.0 << "° C"; produces the string 04e+01° C...
