Can the integer type be generalized? about json11 HOT 3 CLOSED

Hi @seewalker. That kind of a templated approach to generic integers seems doable, but out of scope for json11. Support only for specific numeric types was an early design decision which is explained in a comment here: https://github.com/dropbox/json11/blob/master/json11.hpp#L16

In the interest of maximal compatibility, json11 will implicitly take the number types which it knows are compatible, and require the user to perform explicit casts in cases where truncation/rounding might be necessary.

Thanks for the answer. A remark for anybody who visits this page with the same thoughts I had: as mentioned in the link pretty much any number type can be safely cast as a double so that's the lowest-common denominator solution that makes sense.

That's true for most number types, but be cautious that it's not necessarily safe for a 64-bit (or larger) integer (because a double contains only 53 bits of precision, so would need to round), or for a long double (which would also need to round).
