Number(s) Formatting

First thing to note: native data is string in Jbase. So if you start with multiplying your data by 1, it will be converted to a number, including inner properties like zero suffixes will disappear.

• Rounding an amount according to pre-set formats:

FMT(number, format)

Example:
  Y.VAR = "8" : VM : "12"
  FMTS(Y.VAR,"R2")
=> gives Y.VAR = '8.00':VM:'12.00'

• Rounding an amount according to currency definition:

CALL EB.ROUND.AMOUNT(CCY,CURRENCY.AMT,param,””)

=> param: ‘1’ = non-cash rounding ‘2’ = cash rounding

• or alternatively you can code your own rounding routine:

CALL ROUNDING.TOOL(NUMBER.TO.ROUND,PARAMETER)

• Example of rounding routine that can be called in Enquiries, standard selections, etc…:

LIST F.SPF EVAL ‘SUBR(“ROUNDING.TOOL”,”-123.123456789″,”8″)’ AS MY.RESULT FMT 20L
@ID…      MY.RESULT
SYSTEM   -123.12345679

SUBROUTINE ROUNDING.TOOL(RESULT,YNUM.SIGNED,Y.ROUND.POS)

$INSERT I_COMMON
$INSERT I_EQUATE

* by default return same value
RESULT = NUMBER.TO.ROUND
IF UNASSIGNED(NUMBER.TO.ROUND) THEN RETURN
IF (NUMBER.TO.ROUND = '') THEN RETURN

* default number of decimals to 6
IF UNASSIGNED(Y.ROUND.POS) THEN Y.ROUND.POS = 6
IF (Y.ROUND.POS = '') THEN Y.ROUND.POS = 6

* round number but do not maintains format
IF (NUM(NUMBER.TO.ROUND) AND NUM(Y.ROUND.POS) AND (Y.ROUND.POS GE 0) AND (Y.ROUND.POS LE 9)) THEN
  RESULT = FMT(NUMBER.TO.ROUND,"R":Y.ROUND.POS)
    IF (NUM(RESULT)) THEN ; * NUM accept "+-." as numeric
      RESULT = TRIM(RESULT) ; * remove space
      IF (RESULT NE '+') THEN
        IF (RESULT NE '-') THEN
          IF (RESULT NE '.') THEN
            RESULT = RESULT * 1
          END
        END
      END
    END
END

RETURN
