version:                0.2.0.0
synopsis:
  Number of digits in a number in decimal and hexadecimal representation.
description:
  There are situations when it is necessary to know the length of a number in
  decimal or hexadecimal form. In example when allocating buffer while
  serializing a number in to binary or human readable format.
