e05 - Data Types (Old Err)

This is the fifth video on learning rust together. Today we
touched on data types. I left out the min and max, because that
is your guys homework in a way. In the next video I'll show that.
As always here is the link to the rust book for more reading.

Scalar Types: Integers, floating-point, Boolean and characters

Integers:
Length | Singed | Unsigned
--------+--------+---------
8-bit | i8 | u8
16-bit | i16 | u16
32-bit | i32 | u32
64-bit | i64 | u64
arch | isize | usize

# Literals | Example
-------------+--------
Decimal | 92_222
Hex | 0xff
Octal | 0o77
Binary | 0b1111_0000
Byte (u8) | b'A'

example i8 = -128 to 127
example u8 = 0 - 255

Floats:
32 bit and 64 bit
let x = 2.0 // f64
let y: f32 = 3.0 //f32

Char:
U+0000 - U+D7FF and U+E000 - U+10FFFF
println!("東京");
