/**
More info--
This is for an assignment in which I must use the floor() function to round a variable "number" to
various accuracies. When I try to compile I get:

Error: Conflicting types of (every function starting with round)
Previous declaration of (function starting with round) was here
Error: Too few arguments to function (starting with round)

Any help would be greatly appreciated! Thank you in advance.
