Description

Converts a floating-point value to an unterminated character string, using a specified Format, Precision, and Digits.

FloatToText converts the given floating-point value to its decimal representation, using the specified format, precision, and digits. The Value parameter must be a variable of type Extended or Currency, as indicated by the ValueType parameter. The resulting string of characters is stored in the given buffer, and the returned value is the number of characters stored. The resulting string is not null-terminated.

The first form of FloatToText is not thread-safe, because it uses localization information contained in global variables. The second form of FloatToText, which is thread-safe, refers to localization information contained in the AFormatSettings parameter. Before calling the thread-safe form of FloatToText, you must populate AFormatSettings with localization information. To populate AFormatSettings with a set of default locale values, call TFormatSettings.Create.
