∟Commonly Used Data Types Are Built-in Data Types

This section describes H language built-in data types - commonly used data types.

Commonly used data types are built-in data types.

This reduces the effort for developers to create classes defining commonly used data types.

Built-in data types should include:

integer - Data structure to store integer numbers.
real - Data structure to store real numbers.
currency - Data structure to store currency values of fixed fractional digits.
byte - Data structure to store 8-bit binary data.
bytes - Data structure to store sequences of bytes.
character - Data structure to store Unicode characters.
string - Data structure to store sequences of Unicode characters.
boolean - Data structure to store Boolean values: true and false.
date - Data structure to store Gregorian calendar dates.
time - Data structure to store time instances.
array - Data structure to store lists of data objects.
hash - Data structure to store named data objects.
