0426. Suppose we only allocated 18-bits to the mantissa. What level of precision can we get and why?

Given: 2¹⁸ = 262,144. There are 6 digits in this number, BUT we can not represent ALL 6-digit numbers (e.g., 765,054). We could represent all 5-digit numbers, however. Therefore, we have 5 decimal places of precision.
