How do you know if a number is denormalized?

A number is denormalized if the exponent field contains all 0's and the fraction field does not contain all 0's. Thus denormalized single-precision numbers can be in the range (plus or minus) to inclusive. Denormalized double-precision numbers can be in the range (plus or minus) to inclusive.

Is 0 normalized or denormalized?

Any floating-point number that doesn't fit into this category is said to be denormalized. Note that the number zero has no normalized representation, because it has no non-zero digit to put just to the right of the decimal point.

Is 0 a denormalized number?

"When the exponent field is all zeros, the represented number is in denormalized form. In this case, the exponent value is E = 1 − Bias, and the significand value is M = f , that is, the value of the fraction field without an implied leading 1."

What is the largest denormalized number?

The largest positive denormalized float is 0. 111111111111111111111112 × 2−126.
