本文介绍了ABAP中用于生成伪随机数的类CL_ABAP_RANDOM及其子类，这些类基于Mersenne Twister算法为不同类型的数据生成随机数，包括整型、浮点型和带小数位的打包型。
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_FLOAT for type f
- CL_ABAP_RANDOM_PACKED for type p
- CL_ABAP_RANDOM_PACKED_DECn with n = 1 to 14 for type p with n decimal places.
