CDBL converts a value to the closest DOUBLE-precision value.

## Syntax

*doubleValue#*= CDBL(*expression*)

## Parameters

*expression*is any TYPE of literal or variable numerical value or mathematical calculation.

## Description

- Rounds to the closest DOUBLE floating decimal point value.
- Also can be used to define a value as DOUBLE-precision up to 15 decimals.

## Examples

*Example:* Prints a double-precision version of the single-precision value stored in the variable named A.

454.67 454.6700134277344

- The last 11 numbers in the double-precision number change the value in this example, since A was previously defined to only two-decimal place accuracy.
