Example ABAP Coding
The class circle contains two functional static methods, circumference and area, which work with the constant pi. CLASS circle DEFINITION.
PUBLIC SECTION.
CONSTANTS pi TYPE decfloat34
VALUE '3.141592653589793238462643383279503'.
CLASS-METHODS: circumference IMPORTING r TYPE decfloat34
RETURNING value(c) TYPE decfloat34,
area IMPORTING r TYPE decfloat34
RETURNING value(a) TYPE decfloat34.
ENDCLASS.

CLASS circle IMPLEMENTATION.
METHOD circumference.
c = 2 * pi * r.
ENDMETHOD.
METHOD area.
a = pi * r ** 2.
ENDMETHOD.
ENDCLASS.

DATA: circ TYPE decfloat34,
area TYPE decfloat34,
radius TYPE decfloat34.

START-OF-SELECTION.

radius = '1.00'.
circ = circle=>circumference( radius ).
area = circle=>area( radius ).
