A string representing the value. Depending on the
value, the form may be standard decimal form with a
decimal point separating the whole and fractional
parts or it may be in “scientific notation” form. In some
cases, there will be no decimal point at all, e.g. with
values having no fractional part.
When converting Single values, some special cases are detected resulting in the strings shown in the
table below. See the function SngClass() for more information about the special cases.
