How to get rails to render in json a bigdecimal as a number without a trailing zero

I would like to know how to get rails to render in json a bigdecimal as a number without a trailing zero.

Currently in my app, using as_json Rails renders a bigdecimal value of an active record entity as a number with a decimal, e.g. bigdecimal 2.0 is rendered 2.0 (not a string). I want it to be rendered as 2 (not a string, without trailing zero).

To attempt this, I have made use of jbuilder and used the rails helper method number_with_precision and option strip_insignificant_zeros: true; however, this converts the value to a string. Tacking on to_f to the end makes '2' 2.0.

Is there a way to render in json a bigdecimal as a number without trailing zeros?

Thank you

If fractional part of the number is 0 - just convert to Integer, otherwise convert to Float.

(x.frac.zero? ? x.to_i : x.to_f)
