| 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)"
```
