AutoFormatData

Unit:SDL_stringl
Class: None
Declaration: [1] function AutoFormatData (data: double; SigDig: integer): string;
[2] function AutoFormatData (data: double; SigDig: integer; UseComma: boolean): string;

The function AutoFormatData converts the parameter data to a string using a representation according to the following guidelines: (1) if the absolute value is greater than 10SigDig-1 or less than 0.1 the value is converted to exponential notation. (2) Numbers between those two boundaries are converted using a floating point representation. (3) The number of decimal places is adjusted in a way that SigDig significant digits are used. Any additional digits are rounded off.

AutoFormatData comes in two overloaded forms: version [1] always uses a dot as the decimal separator, while version [2] replaces the dot separator by a comma if the parameter UseComma is TRUE.
