decimal64 

Overview

The decimal64 type represents a subset of the real numbers, which can be represented by decimal numerals.

...

A decimal64 type can be restricted with the "range" statement. 

The "fraction-digits" statement, which is a substatement to the "type" statement, MUST be present if the type is "decimal64".  It takes as an argument an integer between 1 and 18, inclusively. It controls the size of the minimum difference between values of a decimal64 type.

The Minimum and Maximum decimal64 value table for each fraction-digit value.
