simulator.h lost chained reference to math.h

Hello,

Since Rev. 471 the file:
src/simulator/simulator.h
lost its chained reference to math.h through component.h and the compilation stops because of the pow() function (Ubuntu 21.04).

Thank you in advance,
Theodore K.

Thanks.
Should be solved at Rev 475.

But I can't test if reference to math.h is lost somewhere else.
In my system it compiled ok at Rev 471.

I just added math.h to simulator.h and compilation was successful.

Until Rev. 470 the chain was:

simulator.h > circmatrix.h > e-node.h > e-element.h > math.h

Thank you,
Theodore K.

I just added math.h to simulator.h and compilation was successful.

I didn't do this.
I moved pow() and added math.h to simulator.cpp to avoid unnecessary chained includes.
