I had to trick the test suite, i think in the solution "c-exp(1)" is wrong, shouldn't it be pi?

Neha Shaah on 22 Oct 2022

test suite for exp(1) is incorrect

Matt Tearle on 24 Oct 2022

I don't understand the comments about exp(1). "e" (exp(1)) is listed as one of the constants in the problem statement. Its value is 2.7183... So an input of 2.5 should return e, as shown in the examples (being closer to 2.5 than sqrt(2) = 1.414...)
