For example, in 32-bit floating point, 8 bits are used for the exponent, and the
exponent bias is 127. So the maximum representable unbiased exponent is 128.

The assembler preserves all the bits of a NaN value. For example, the encoding

The disassembler prints infinite, NaN, and subnormal values in hexadecimal form.
Zero and normal values are printed in decimal form with enough digits
