What is e^(1.000000001)?
Please enter in decimal with 7 places.
(For example, if the answer was 2.71828183... the flag would be 2.7182818 )
In classic PlaidCTF fashion we have another "X are hard" challenge. A quick google search for logarithm bug
gives us http://www.datamath.org/Story/LogarithmBug.htm. Further down the page we see the logarithm section we care about The yx Function. Our n value is 1,000,000,000 for 9 places, and in the table we see 2.7191928.
