Learning Julia

Integers, bits, bytes, and bools

Integers, bits, bytes, bools, and floating point numbers are used in arithmetic operations. Built-in representations of them are called as numeric primitives, and numeric literals are their representations as values in code.

Let’s understand Julia’s primitive numeric types. The following is a table of Integer types, which includes bits, bytes, and bool:

Type	Number of bits	Smallest value	Largest value
Int8	8	-2^7	2^7 - 1
UInt8	8	0	2^8 - 1
Int16	16	-2^15	2^15 - 1
UInt16	16	0	2^16 - 1
Int32	32	-2^31	2^31 - 1
UInt32	32	0	2^32 - 1
Int64	64	-2^63	2^63 - 1
UInt64	64	0	2^64 - 1
Int128	128	-2^127	2^127 - 1
UInt128	128	0	2^128 - 1
Bool	8	false (0)	true (1)

 

The UInt type refers to unsigned ...
