number ↔ Primitive Value to rep FP64 numeric data Type

FP64​

64-bit Double-Precision Floating-Point Format

can store Hexadecimal, binary or Octal 

let hex: number = 0xf00d;
let binary: number = 0b1010;
let octal: number = 0o744;

Octal​

number system with base 8

Hexadecimal​

number system in base 16 rep by 16 symbols (0-9 & A-F)
