Question

I somehow have to keep my program running until the output of the exponent function exceeds the input value, and then compare that to the previous output of the exponent function. How would I do something like that, even if in just pseudocode?

Answer 1

1. Find logarithm to base 2 from given number => x := log (2, input)
2. Round the value acquired in step 1 both up and down => y := round(x), z := round(x) + 1
3. Find 2^y, 2^z, compare them both with input and choose the one that suits better
