FloatToStr function

Declaration

function FloatToStr(Value: Extended): string

Description

FloatToStr converts the floating point variable Value to a string representation. It will choose the shortest possible notation of the two following formats:

Fixed format

will represent the string in fixed notation,

Decimal format

will represent the string in scientific notation.

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.

Errors

None.
