[[Property:title|More precision]] [[Property:weight|4]] [[Property:uuid|fadf5bc2-bb72-f681-b9c4-bab7f0633209]] The classes TIME and TIME_DURATION are designed to deal with time in high precision, limited only by platform numerical representation. The classes TIME and TIME_DURATION have an attribute fine_second of type DOUBLE which allows high precision. This attribute represents the number of seconds with fractions. From fine_second are calculated the values for second and fractional_second. second is the truncated-to-integer part of fine_second and fractional_second is the fractional part of fine_second. When fine_second is positive, 3.55 for example, second and fractional_second are both positive (3 and 0.55, respectively). When fine_second is negative (- 3.55 for example), then second and fractional_second are both negative (- 3 and - 0.55). Manipulation on second and fractional_second are in fact always made through fine_second. Users who do not want to deal with precision do not need to care about this. Features dealing with fine_second and fractional_second are described here. ====Creation (common to TIME, TIME_DURATION)==== * make_fine is similar to make except that it takes a DOUBLE for its third argument (instead of an INTEGER, as is the case with make). fine_second is then set to this value. * make_by_fine_seconds is similar to make_by_seconds except that it takes a DOUBLE for an argument (instead of an INTEGER, as is the case withmake_by_seconds). ====Measurement and access==== In TIME: * fine_seconds looks like seconds but it contains fractions. In TIME_DURATION: * fine_seconds_count looks like seconds_count but it contains fractions. ====Element change==== * Set fine_second directly with set_fine_second. * Set fractional_second directly with set_fractionals. {{note|Use of the feature set_second (in either TIME and TIME_DURATION) will result in fractional_second having a value of zero. }} ====Operations==== * fine_second_add looks like second_add except that it takes a DOUBLE as an argument.
