Here is the function code...
pt(x)
Func
Return approx(x/100)
EndFunc

Well, 100+pt(36) = 136 as you have above is just the same as 100+36=136
and
100 - pt(36) = 64 is the same as 100-36=64
So I really don't get why you have it above as pt(36) when you could just
put 36 in there for it instead ???
However, a percent just means "out of 100", so the code above that I did
returns x divided by 100 to get it into the percent form, then approx(
just makes it so it will always show a decimal, instead of 9/25 for .36
etc...
Hope that helps!
