First, apologies for what is probably a simple question but it's just not "clicking" for me.
I'm putting together a spreadsheet that I can use to calculate resistor values for a debounce circuit, as given in the Ganselle Debounce Guide (). For some reason my brain has hit this equation and stopped working, leaving me rather embarrased and grateful for any help!
I've been reading through (amongst other things) the Ganselle guide and a few threads on this board. Everyone mentions the following formula, and discuss/define most of it, but always seems to leave one bit unmentioned.
I'm trying to work out what In() is, and what it is doing? My apologies if the answer is in fact in the other thread but I've either missed it or not understood what I was reading

Taken from this post: https://forum.allaboutcircuits.com/showpost.php?p=182602&postcount=7
R = t / ( C*In(Vcc/Vc) ) = 5s / ( 5uF * In(9/4.5) )= 5/(5uF*0.693)=5/3.465u=1.44MΩ=1.5MΩ
