Round is different from the bin() function in
that the round() function rounds a number to a specific number of digits while the bin() function rounds the value to an integer multiple of a given bin size. For example, round(2.15, 1) returns 2.2 while bin(2.15, 1) returns 2.
Examples
round(2.98765, 3) // 2.988
round(2.15, 1) // 2.2
round(2.15) // 2 // equivalent to round(2.15, 0)
round(-50.55, -2) // -100
round(21.5, -1) // 20
