Revision as of 16:50, 31 August 2009 by 63.116.159.137 (talk) (Created page with ''''Purpose:''' To convert x to a double-precision number. '''Syntax:''' CDBL(x) '''Comments:''' x must be a numeric expression. '''Example:''' A=454.67 PRINT A; CDBL(A) 454…')

**Purpose:**
To convert x to a double-precision number.

**Syntax:**
CDBL(x)
**Comments:**
x must be a numeric expression.

**Example:**

A=454.67 PRINT A; CDBL(A)

454.67 454.6700134277344

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

The last 11 numbers in the double-precision number have no meaning in this example, since A was previously defined to only two-decimal place accuracy.

Note

See the CINT and CSNG functions for converting numbers to integer and single precision, respectively.
