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