# CDBL Function

#### Purpose:

To convert x to a double-precision number.

#### Syntax:

    CDBL(x)

#### Comments:

x must be a numeric expression.

#### Example:

    10 A=454.67
    20 PRINT A; CDBL(A)
    RUN
     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.
