Description

Returns a boolean value representing the success code for converting a string to a floating point value.

This method is overloaded:

• Places the resulting Double number in Value, and returns True if the conversion was successful, False otherwise.
• Places the resulting Double number in Value, and returns True if the conversion was successful, False otherwise. This form of TryParse is thread-safe, due to the localization information contained in the AFormatSettings parameter.
