 === Description
-Computes the value of the specified bit (bit 0 is 1, bit 1 is 2, bit 2 is 4, etc.).
+Computes the value of the specified bit (bit 0 is 1, bit 1 is 2, bit 2 is 4, etc). The value returned is 2^n where n is an integer input.

+=== Notes and Warnings
+The variable `n` must be an integer type. float and double will return an error and the program will not compile.
+
+The maximum value that can be returned by `bit(n)` is 2^31 = 2147483648 after which 0 is returned.
