√ Form Calculation Range
The allowable display ranges of the √ form calculation result are shown below.
± a√b, ± d ± a√b, ± a√bc ± d√ef
1 ≤ a < 100, 1 < b < 1000, 1 ≤ c < 100
0 ≤ d < 100, 0 ≤ e < 1000, 1 ≤ f < 100
Example:
10√2 + 15 × 3√3 = 45√3 + 10√2 ... Displayed in √ form
99√999 (= 297√111) = 3129.089165 ... Displayed as a decimal value
