The length of the floating point field must be specified

as either 4 or 8 bytes. The range of values allowed for

a positive floating-point field are:

4 bytes 1.175 494 4 E-38 (MIN)

3.402 823 5 E+38 (MAX)

8 bytes 2.225 073 858 507 201 E-308 (MIN)

1.797 693 134 862 315 E+308 (MAX)

My question is: how it calculates?

Thanks.
