A simple widget high-performance calculator.
Tap the formula display field to open the formula input screen. Enter the formula and use it.
∙ Registered functions and physical constants can be selected from the list and entered.
Entry by using IME is also possible by tapping the text editor.
specification)
・ The size is 4 × 1.
・ Formula input formula.
・ Complex number meter is available. (Use i for the imaginary unit. You can omit the x symbol only when it appears before or after the numerical value.)
・ Functions such as trigonometric function, inverse trigonometric function, exponential calculation, logarithmic calculation, absolute value, complex declination, angle and arc change can be used.
・ There are more than 40 constants registered, such as pi and number of napiers. (Indicated with a symbol with #.)
Example: # π: Pi, #c: Speed of light in vacuum
・ The notation of angle can be switched between angle (DEG) and arc degree (RAD).

○ Notation of arrays, vectors, and matrices
· Array notation
{1,2,3,4,5,6,7,8,9,10}
○ Vector notation
{1,2}
○ Matrix notation
| 1 2 3 |
| 4 5 6 | → {{1,2,3}, {4,5,6}, {7,8,9}}
| 7 8 9 |
○ Derivative / integral calculation
( x 2 ) 'with x = 1 → diff (1, pow (x, 2) )
∫ x 2 d x calculated with x = 0 to 1 → ∫ (0,1, pow (x, 2))
○ Sum and sum
Calculate Σ x 2 with integer x = 0 to 10 → Σ (0,10, pow (x , 2))
Π x 2 is calculated with integer x = 1 to 10 → Π (1,10, pow (x , 2))
○ Recursion formula calculation
x 0 = 1
x 1 = 2
x n = x n < / i> -1 + x n -2
n = 10
→ recur (10, {1,2}, x1 + x2)
○ Logical operations
True → 1, False → 0
