@brief helper class to create locales with decimal point

This struct is used a default locale during the JSON serialization. JSON

requires the decimal point to be `.`, so this function overloads the

||||||
`do_decimal_point()` function to return `.`. This function is called by

|

float-to-string conversions to retrieve the decimal separator between integer
|
|
||||||
and fractional parts.

@brief helper class to create locales with decimal point
|
|
||||||
|
|

This struct is used a default locale during the JSON serialization. JSON
|
|
||||||
requires the decimal point to be `.`, so this function overloads the
|
|
||||||
`do_decimal_point()` function to return `.`. This function is called by
|
|
||||||
float-to-string conversions to retrieve the decimal separator between integer
|
|
||||||
and fractional parts.
