What is the maximum number that can be written in two bytes in floating point format?

A floating point number needs to be written two values – the mantissa and the value. In modern systems (32 bits) double precision (64 bits) is used. Then we get that the mantissa will take 53 bits, the indicator – 11 bits. Therefore, the range of numbers that can be displayed in this way: from 4.94 * 10-324 to 1.79 * 10 +308 (from 2-52 × 2-1022 to ~ 1 × 21024)
