Takes any data type and returns an INT64 value, if the conversion is possible. This function takes most common data types except for RAW and MEMPTR.

Syntax

INT64 ( expression )
expression
A constant, field name, variable name, or expression whose value can be of any data type except for RAW and MEMPTR. The function behaves as described for the following data types:
  • If the value of expression is a CHARACTER, it must be valid for conversion into a number. Scientific notation format is allowed. For example, "1.67" and "1.67E+3" are valid.
  • If expression is an object reference (CLASS), the result is the ABL-generated ID for the class instance.
  • If expression is a reference to an instance of an enum, the result is the underlying numeric value of that instance.
  • If expression is a LOGICAL, the result is 0 if expression is FALSE and the result is 1 if expression is TRUE.
  • If expression is a DATE, the result is the number of days from 1/1/4713 B.C. to that day. If expression is the Unknown value (?), the result is the Unknown value (?).

Example

The following example demonstrates how to use the INT64 function to convert a variety of data types to the INT64 data type:

r-int64.p 

DEFINE VARIABLE myint   AS INTEGER   NO-UNDO
  INITIAL 2000000000 FORMAT "->>,>>>,>>>,>>>".
DEFINE VARIABLE myint64 AS INT64     NO-UNDO
  INITIAL 333444555666 FORMAT "->>,>>>,>>>,>>>,>>>".
DEFINE VARIABLE mychar  AS CHARACTER NO-UNDO INITIAL "2234.3".
DEFINE VARIABLE mydec   AS DECIMAL   NO-UNDO INITIAL "240,234.05".
DEFINE VARIABLE mybool  AS LOGICAL   NO-UNDO INITIAL TRUE.
DEFINE VARIABLE mydate  AS DATE      NO-UNDO INITIAL 01/01/06.
DEFINE VARIABLE myhdl   AS HANDLE    NO-UNDO.

DEFINE FRAME x WITH TITLE "emptyframe".
myhdl = FRAME x:handle.

MESSAGE "integer of integer expression is" INTEGER(myint).
MESSAGE "integer of int64 expression is" INTEGER(myint64 - 333000000000).
MESSAGE "integer of int64 >2gig is" INTEGER(myint64).
MESSAGE "integer of char is" INTEGER(mychar).
MESSAGE "integer of dec is" INTEGER(mydec).
MESSAGE "integer of bool is" INTEGER(mybool).
MESSAGE "integer of date is" INTEGER(mydate).
MESSAGE "integer of handle is" INTEGER(myhdl).
MESSAGE " ".

MESSAGE "int64 of integer expression is" INT64(myint).
MESSAGE "int64 of int64 expression is" INT64(myint64 - 333000000000).
MESSAGE "int64 of int64 >2gig is" INT64(myint64).

MESSAGE "int64 of dec is" INT64(mydec).
