radix in toString

[bowenwang1996]

Is there plan to support radix in toString for integer types?

[dcodeIO]

Of course, yeah, is on todo but afaik nobody is currently working on it. Code responsible for this and similar things lives in std/internal/number.

But this change little bit with upcoming rework runtime (#535) branch

Is any workaround exists for it?

This is working now, but if you wrap it in a function then the type must not be number but one of the explicit ones like u8. I think this is a bug.

function hex(n: number): string {
  return '0x' + n.toString(16)
}

number in AssemblyScript is just alias of f64. We can't implement conversions from float to string in hexadecimal format because it's unusable. For example in JS: (1.2345e10).toString(16) == "2dfd1c040". It's not hexadecimal float points (in this case we would have seen 0x1.6fe8e02p+33), it's something very legacy which we try to avoid

I see, I guess this is the correct approach:

function hex<T>(n: T): string {
  return '0x' + n.toString(16)
}

This compiles and works fine, although I get a typescript error in the editor: "Property 'toString' does not exist on type 'T'."

function hex<T extends number>(n: T): string {
  return '0x' + n.toString(16);
}
