I128(-42) instead of I64(-42)

[azemlya]

Another thing I don't understand:

{% set m = {
    "key1": 42,
    "key2": -42,
    "key3": 42.424242,
    "key4": -42.424242,
} %}

In the debug mode, I take a look and see I128(-42).

Map(String("key1"): I64(42), String("key2"): I128(-42), String("key3"): F64(42.424242), String("key4"): F64(-42.424242))

Why? What is the reason for this?

It's using i128 internally for all operations on integers, and -42 is one. Floats are always f64 so it's not changing anything for them

[azemlya]

I made my own filter that generates TOML data. But, TOML format does not support I128. An error occurs when integers are negative.

You can probably cast them to i64. Having a single type of integers for numbers is easier internally for operation results. I might need to add some impl for filters so it does the conversion automatically though, I can't remember if it's already in
