Pattern: Inconsistent numeric literal case

Issue: -

Description

Using lowercase letters in numeric literals makes them harder to differentiate from identifiers. Hexadecimal, binary, and octal literals should use uppercase letters for better readability.

Examples

Example of incorrect code:

const foo = 0xff;
const foo = 0xffn;
const foo = 0b10;
const foo = 0o76;
const foo = 2e-5;

Example of correct code:

const foo = 0xFF;
const foo = 0xFFn;
const foo = 0b10;
const foo = 0o76;
const foo = 2E5;
