Talk:Bell numbers

From Rosetta Code

size of Bell numbers[edit]

For the sake of curiosity,   I let the REXX program run wild and had it record the size of some Bell numbers.

Here are the results:

             Bell(    99)  has     115  decimal digits.
             Bell(   199)  has     275  decimal digits.
             Bell(   299)  has     453  decimal digits.
