FloatToStr converts the floating point variable Value to a string representation. It will choose the shortest possible notation of the two following formats:
More information on these formats can be found in FloatToStrF. FloatToStr is completely equivalent to the following call:
FloatToStrF(Value, ffGeneral,15, 0);
Note that on unix systems, the localization support must be enabled explicitly, see Localization.
