CDec

Function that converts an expression into a Decimal (Number.)

Syntax
      CDec (expression)

The Decimal data type stores numbers from -10^²⁸-1 through 10^²⁸-1.
If an ADP file is used (with SQL Server) this increases to -10^³⁸-1 through 10^³⁸-1

CDec cannot handle Null values, use Nz() to convert Nulls to a valid number.

Unlike most similar functions, you cannot use CDec() in a Query, the workaround is to write a custom function.

Example

Dim dblDemo as Double

dblDemo = CDec(12 * 0.000001)

“People have a peculiar pleasure in making converts, that is, in causing others to enjoy what they enjoy, thus finding their own likeness represented and reflected back to them” ~ Johann Wolfgang von Goethe
