My own maths thing I(x) is B I G
I(x) = x^x^x and so on x+1 times
I(0)=0
I(1)=1^1=1
I(2)=2^2^2=2^4=16
I(3)=3^3^3^3=3^3^27=3^7625597484982=a number with over 36 TRILLION DIGITS
I(x) where x is Bigger than 3 is in computable
I(0.5)=0.25
I(1.5)=1.5^0.75≈1.3554

My own maths thing I(x) is B I G

I(x) = x^x^x and so on x+1 times

I(0)=0

I(1)=1^1=1

I(2)=2^2^2=2^4=16

I(3)=3^3^3^3=3^3^27=3^7625597484982=a number with over 36 TRILLION DIGITS

I(x) where x is Bigger than 3 is in computable

I(0.5)=0.25

I(1.5)=1.5^0.75≈1.3554

Bye!
