1. A non-transitory computer-readable recording medium having stored therein a coding program that causes a computer to execute a process comprising:
- coding a numerical value into a numeric code of base-2n representation; and
generating code data that have been added with an instantaneous code that indicates a number of digits of the base-2n representation of the numerical value, the instantaneous code having bits associated with the numbers of digits from a head bit in an order of the number of digits, wherein“
n”
is a natural number equal to or greater than 1.

Abstract
A non-transitory computer-readable recording medium having stored therein a coding program that causes a computer to execute a process. The process includes coding a numerical value to be coded, into a numeric code of base-2n representation; and generating code data that have been added with an instantaneous code indicating the number of digits of the base-2n representation of the numerical value to be coded, wherein “n” is a natural number equal to or greater than 1.
