Tapered floating point

Variant of floating-point numbers in computers

In computing, tapered floating point (TFP) is a format similar to floating point, but with variable-sized entries for the significand and exponent instead of the fixed-length entries found in normal floating-point formats. In addition to this, tapered floating-point formats provide a fixed-size pointer entry indicating the number of digits in the exponent entry. The number of digits of the significand entry results from the difference of the fixed total length minus the length of the exponent and pointer entries.
