Purpose: To convert x to a double-precision number.
Comments: x must be a numeric expression.
A=454.67 PRINT A; CDBL(A)
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.
See the CINT and CSNG functions for converting numbers to integer and single precision, respectively.
