GameMaker Functions perfomance hit

[I'm lost]

Greetings,
I would like to know if anyone knows the perfomance hit of two functions, because recently I'm using them quite often and I think they might slow down my game i bit more that I would expect

The functions I'm talking about are:
lengthdir_x/y()
device_mouse_x/y_to_gui()

Are those some unusualy demanding functions?

Thank you in advance for your reply

The ones you showed are not particularly heavy functions. If you really want to know where performance hits come from, do it the proper way and learn to use the profiler in debug mode.
