my_round(number, integer): Based on the built-in round(...) function. Takes an integer or float and returns a rounded float value that is the number rounded to the second argument's decimal place. First argument can be any float or integer. Second argument must be an integer. Examples: my_round(1234.5678, 2) and round(1234.5678, 2) should return 1234.57. my_round(1234.5678, -2) and round(1234.5678, -2) should return 1200.0.
