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.
