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.
