Emit Numerical Literal with different TokenFlags

[Kingwl]

Search Terms

emitter, numerical

Suggestion

Currently, all Numerical Literal has been emitted as Decimal number.
Hope to allow emit Hex Literal or Binary Literal etc

Use Cases

ts.createLiteral('2', TokenFlags.BinarySpecifier) // 0b10

That is useful to create a codegen

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.
