Modify LFO

Hello,
I am trying to manage for hours but I am unsuccesful on this.
I want to LFO node to create values 0 to 100 and then goes back 100 to 0.
Is there an another way to this rather then LFO.
I multiply the output with 100 that is easy but I cant manage to make it back and forth .
Thanks

Hi.

You cound use a waveshaper node under your lfo.

Worked like a charm, thanks
