Random Numbers

The class CL_ABAP_RANDOM calls the pseudo random number generator Mersenne Twister for different numeric types.

For the one-dimensional case, the following special classes generate random numbers for the different numeric types:

• CL_ABAP_RANDOM_INT for type i

• CL_ABAP_RANDOM_INT8 for type int8

• CL_ABAP_RANDOM_FLOAT for type f

• CL_ABAP_RANDOM_PACKED for type p

• CL_ABAP_RANDOM_PACKED_DEC1 to CL_ABAP_RANDOM_PACKED_DEC14 for type p with 1 to 14 decimal places.

• CL_ABAP_RANDOM_DECFLOAT16 for type decfloat16

• CL_ABAP_RANDOM_DECFLOAT34 for type decfloat34

Example

Creates a pseudo random number of the type i between 1 and 100 (initialized by the system time).

DATA(r) = cl_abap_random_int=>create( seed = CONV i( sy-uzeit )
                                      min  = 1
                                      max = 100 ).
