Json Real Precision setting

Gary Gasson

Hi,

If I have a value (float_32) 22.648274618 and I am using Json to output my data I use the real function of Json. This works great but now I would like the Json output to only 22.648 and not the whole number.

Is this possible and how?

    What do you mean by that?

    Are you using some library on your ARM microcontroller to create this JSON ?

    If so, what does its documentation tell you?

    If not, then please provide more detail of how you are creating the JSON output.
