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). See
GCD, LCM: GCD determines the greatest common divisor of two values,
while LCM determines the least common multiple. See
Int: Extracts the integer part of a value. See
Intg: Determines the largest integer that does not exceed a value. See
Note: Using functions can slow down a calculation, which may delay display
of the result. Do not perform any subsequent operation while waiting for the
calculation result to appear. To interrupt an ongoing calculation before its
result appears, press A.
