CDBL Function
 ----------------------------------------------------------------------------


 Action

 Converts a numeric expression to a double-precision value.


 Syntax

  CDBL( numeric-expression)


 Remarks

 The argument  numeric-expression can be any numeric expression. This
 function has the same effect as assigning the numeric expression to a
 double-precision variable.

 The results of  CDBL are no more accurate than the original expression. The
 added digits of precision are not significant unless the expression is
 calculated with double-precision accuracy.

 Example

 The following example demonstrates how the precision of the argument affects
 the value returned by  CDBL.

 X = 7-9
 X# = 7-9
 PRINT X
 ' Both X# and CDBL(X) will be accurate to only 7 decimal
 ' places, because 7-9 is evaluated in single precision.
 PRINT X#
 PRINT CDBL(X)
 PRINT 7#-9#' Accurate to 15 decimal places.
