MODUL(<real expression>, <real expression>);Returns the remainder that results from dividing the value of the first <real expression> by the second <real expression>, when the division is performed until the units in the quotient.
Example: MODUL(804, 364.25) is computed by dividing 804 / 364.25
= 2
MODUL(804, 364.25) is computed by: 804 - 2 * 364.25 = 75.5; (assuming
the year equal to 364.25 days, 804 days are 2 years plus 75.5 days)
