#
Parse( string $rawInput )
Try to parse floating point number from raw user input string
by locale conventions by Intl extension or by automatic
floating point detection (which looks more successful).
If there is not possible to get float value, return NULL.
Try to parse floating point number from raw user input string
by locale conventions by Intl extension or by automatic
floating point detection (which looks more successful).
If there is not possible to get float value, return NULL.
If Intl extension installed and if Intl extension parsing preferred,
try to parse by Intl extension integer first, than floating point number,
but always return floating point number type.
If not preferred or not installed, try to determinate floating point in
user input string automatically and use PHP floatval() to parse the result.
If parsing by floatval returns NULL and Intl extension is installed
but not preferred, try to parse user input by Intl extension after it.
This function do not throw any exception outside.
All possible exceptions are caught inside the class.
