CDBL converts a value to the closest DOUBLE-precision value.


Syntax

doubleValue# = CDBL(expression)


Parameters

  • expression is any TYPE of literal or variable numerical value or mathematical calculation.


Description

  • Rounds to the closest DOUBLE floating decimal point value.
  • Also can be used to define a value as DOUBLE-precision up to 15 decimals.


Examples

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

 A = 454.67
 PRINT A; CDBL(A)
 454.67 454.6700134277344
The last 11 numbers in the double-precision number change the value in this example, since A was previously defined to only two-decimal place accuracy.
