Detailed Description
template<typename T>
struct pni::io::float_policy< T >
Formatting policy for real numbers. The current policy differs from the C++ default in two ways
- by default always the scientific format is used
- if required the ouput precision is the full precision of the type
The idea behind this policy is to avoid accidental truncations of floating point numbers during ASCII output. This policy is used in all cases where a floating point type should be converted to a character string.
- Template Parameters
-
T floating point type
