Rounding Function (Rnd)
The argument of this function is made a decimal value and then rounded
in accordance with the current number of display digits setting (Norm, Fix,
or Sci).
With Norm 1 or Norm 2, the argument is rounded off to 10 digits.
With Fix and Sci, the argument is rounded off to the specified digit.
When Fix 3 is the display digits setting, for example, the result of 10 ÷ 3 is
displayed as 3,333, while the calculator maintains a value of
3,33333333333333 (15 digits) internally for calculation.
In the case of Rnd(10÷3) = 3,333 (with Fix 3), both the displayed value
and the calculator's internal value become 3,333.
Because of this a series of calculations will produce different results
depending on whether Rnd is used (Rnd(10÷3) × 3 = 9,999) or not used
(10 ÷ 3 × 3 = 10,000).
Example:
To perform the following calculations when Fix 3 is selected for
the number of display digits: 10 ÷ 3 × 3 and Rnd(10 ÷ 3) × 3 (LineIO)
Greatest Common Divisor (GCD) and
Least Common Multiple (LCM)
Greatest Common Divisor (GCD)
GCD determines the greatest common divisor of two values.
Example:
To determine the greatest common divisor of 28 and 35
(GCD) 28
Least Common Multiple (LCM)
LCM determines the least common multiple of two values.
Example:
To determine the least common multiple of 9 and 15
