calculate factorial with recursive methods

[ABAPDos]

Can someone show an ABAP code to calculate Factorial, using recursive methods ?

It will be helpful for best understanding and coding methods in ABAP.

Thanks in advanced

Look at a method such as CL_EHFND_ACE_FORMULA_CALC_DAC=>FACTORIAL.

(NB: this class contains also a method FACTORIAL_NOT_RECURSIVE)
