Introduction

New datatypes

Datatypes are the most useful building blocks in Exponential 3. To create any attribute in any class, you need to choose a suitable datatype to represent your attribute. The concept of Exponential datatypes is not exactly the same as datatypes in common programming languages although Exponential has some basic datatypes such as integer, float and textline which is actually a string type. Datatypes in Exponential are defined as fundamental and common elements which can build complex products on the Internet.
