    you are always looking for the integer just to the left of the value or itself if x does not equal the value.

    so for positive values 4.3, 4.4, etc., the integer is 4, the greatest integer LESS THAN 5.3

    so for negative values -4.4 -4.3, etc., the integer is -5, the greatest integer LESS THAN -4.3
