H A D | exprtkTools.hpp | 0ab9d838 Tue Jul 19 02:12:50 CDT 2022 Lei YU <yulei.sh@bytedance.com> exprkt: Add maxIgnoreNaN to ignore the NaN value
The max function in exprtk uses std::max() to get the max value. Comparing a value with nan has special rule and is not expected in virtual sensor's case. E.g. `max(nan, 1)` gives `nan`.
Adding a new exprkt function `maxIgnoreNaN` to handle the above case so that it ignores all `nan` values. If all values are `nan` then it returns `nan`, otherwise it returns the max value of the valid values.
Example usage in json config: ``` "Expression": "maxIgnoreNaN(T0, T1, T2, T3)" ```
