This is an incorrect value.

This is the correct value (within Float precision).
As the Base gets larger, the problem is more visible:
> (BigDecimal("22222") ** BigDecimal("3.5")).to_i
=3D> 1635840670000000
Wrong value, number of trailing zeroes increase.
> 22222 ** 3.5
=3D> 1635840670214066.5 (nearing maximum Float precision)
