10066,math::round broken for some integer types/values,andrew.bell.ia@…,John Maddock,"The current code takes the input (which may be an int type) and adds/subtracts .5f, which may cause precision to be lost as the integer is converted to a float.  math::round should essentially be a noop when the input type is integral.
