√  Form Calculation Range

The allowable display ranges of the √  form calculation result are shown below.

± a√b, ± d ± a√b, ± ^a√b_c ± ^d√e_f

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
