Abstract

A system for compressing numbers represented in clear text format of a Standard Page Description Language (SPDL) in which numbers are compressed to a binary format represented by N/2.sup.r. Only numbers which are integers or have a decimal portion following a certain format can be compressed using this format. If the number is an integer, it could be converted setting N equal to the number and r equal to zero. If the number contains a decimal portion, the number is doubled and then checked to see if it has become an integer. If it has not become an integer, it is repeatedly doubled until the integer portion N or r go out of range. A second embodiment of the compression system operates in a similar manner if the number to be compressed is an integer. If it is not an integer, the decimal portion of the number is broken into groups having four consecutive digits. The right most group of digits is examined to determine if it is characteristics which allow compression using the N/2.sup.r format. If the proper characteristics exists, the right most group of digits is multiplied by a power of two which results in a product having zeros in the ones, tens, hundreds, and thousands positions. This process continues until all groups of digits to the right of the decimal are eliminated or a group of digits is encountered which does not permit compression into the N/2.sup.r format.
