Convert Certain Types to a String
Syntax
`# include <cppad/utility/to_string.hpp>
` `s = to_string(value)` .
See Also
base_to_string , ad_to_string
Purpose
This routine is similar to the C++11 routine `std::to_string` with the following differences:

1. It works with C++98.
2. It has been extended to the fundamental floating point types.
3. It has specifications for extending to an arbitrary type; see base_to_string .
4. If `<cppad/cppad.hpp>` is included, and it has been extended to a `Base` type, it automatically extends to the AD types above Base .

value
Integer
The argument `value` can have the following prototype `
const Integer& value
` where `Integer` is any of the fundamental integer types; e.g., `short int` and `unsigned long`. Note that if C++11 is supported by this compilation, `unsigned long long` is also a fundamental integer type.
Float
The argument `value` can have the following prototype `
const Float& value
` where `Float` is any of the fundamental floating point types; i.e., `float`, `double`, and `long double`.
s
The return value has prototype `
std::string s
` and contains a representation of the specified `value` .
Integer
If `value` is an `Integer` , the representation is equivalent to `os << value` where `os` is an `std::ostringstream`.
Float
If `value` is a `Float` , enough digits are used in the representation so that the result is accurate to withing round off error.
Example
The file to_string.cpp contains an example and test of this routine. It returns true if it succeeds and false otherwise.
