Description

ToString will convert AValue (or Self in the plain method version) to a string. Optionally FormatSettings can be specified, to be able to specify the decimal separator character to use.

Additionally, a precision APrecision and number of digits ADigits can be specified, in conjunction with a AFormat parameter to specify the form in which the floating-point value must be represented. (see TFloatFormat for an explanation of the various values). In this case, FloatToStrF is used to format the value. In the absence of these parameters, FloatToStr is called.
