Approaches for compressing exponents of floating point values include accumulating a distribution of values of exponents of the first set of floating point values, and compressing the exponents of the first set of floating point values into a compressed exponent bit-width as a function of a compressed exponent bias. The compressed exponent bit-width and the compressed exponent bias are adjusted based on the distribution of values of exponents of the first set of floating point values. The distribution of values of exponents of the first set of floating point values is accumulated with values of exponents of a second set of floating point values that is input in subsequent time period. The exponents of second set of floating point values are compressed into the compressed exponent bit-width as a function of the compressed exponent bias after the adjusting of the compressed exponent bit-width and the compressed exponent bias.
