Prerequisites[edit]

Data Types[edit]

Data types (or sometimes just types) provide a means to classify data so that the REPL or ECRD environment can properly interpret the data. A data type provides the connection between the binary format in which all data is ultimately represented in a digital computer (whether that be in main memory, a register, on disk, or in transit across a network) and the representation of that data for humans. Further, legal operations on the associated data is determined by its type. Let’s consider a few bytes in memory:

07AE: 0 1 0 0 0 0 0 1
07AF: 0 1 0 1 1 0 0 0

	Coming Soon
	Add section describing all basic types, including sized integers (Int8, etc.) and unsigned integers of various sizes.

Constants[edit]

let pi = 3.14159265358979323846
let e = 2.718281828459
let g0 = 9.80665 (in m/s2)

 == Constants ==
-A '''constant''' is a value which will not be altered as a program executes. A '''named constant''' is a constant associated with an identifier which can subsequently be used to refer to the value of the constant. In the below examples, pi, e, and g0 are all named constants:
