Nearest Integer Function
The nearest integer function nint(x) of 
, also called Nint or the Round function, is defined such that
is the Integer closest to . It is shown as the thin solid curve in the above plot. Note that while isused to denote the nearest integer function in this work, is more commonly used to denote the Floor Function
