calculator features:
-equation string, e.g.
1+2x3-4÷5.0-.2+1+2^5 = 39.0
-compound operators and precedence +, -, x, ÷, ^, e.g.
1+2x3÷4-5 = -3
1+2x3÷4.0-5 = -2.5
2^10 = 1024
6--5x3 = 21
-use parenthesis ( ) as highest operator precedence. e.g.
(3+6)x2-3÷2 = 17
-long press to copy result and paste to other app, e.g.
17.0+2x3-4x5÷6+7-8x9÷5+6x7-5 = 50.0
-Integer operation, e.g.
11÷2 = 5.0
-Floating point operation, e.g.
11.0÷2 = 5.5
11÷2.0 = 5.5
-perform x^y, e.g.
2^16 = 65536.0
-perform square root, e.g. √625,
tap √ , tap 6 2 5, tap = , result: √625 = 25.0
-compute %, e.g. to find 5% of 300.
tap 5, tap %, tap x, tap 3 0 0, tap =, result: 0.05x300 = 15.0
-compute logarithm base 10, e.g. log1000
tap log, tap 1 000, tap =, result: log1000 = 3.0
-compute factorial, e.g. 5!
tap 5, tap !, result: 5! = 120.0
-compute inverse of x or 1/x, e.g. inverse of 25
tap 25, tap 1/x, result: 1/25 = 0.04
-compute area of a circle with radius 5, e.g.
tap 2, tap x, tap Pi, tap x, tap 5, tap =, result: 2xPix5 = 31.4159
-Continuous computation, e.g. to compute 7.5% of 800 then add by 1000.
tap 7.5, tap %, tap x, tap 800, tap +, tap 1 000, tap =, result: 0.075x800+1000 = 1060.0
-Tap share button to share the result of the computation to other apps.
-Tap M+ to add result in memory
-Tap M- to subtract result in memory
-Tap MC to clear result from memory.
-Tap MR to recall result from memory.

Note:
-Operators (, ), +, -, x, ÷, and ^ can combine into a long equation string. e.g.
17+2x3^2-4x5÷6.0+(7-8)x9÷5.0+6x7-5

-Computation follows operator precedence, e.g.
1+2x3-2^3+1 = 0.0
2x(3+4)÷3.0+5 = 9.666666666666668

-Operators !, % and 1/x can only be used in a single operation or first operator in mixed operation, e.g.
5!, 6%, but not 2 + 5!, not 20 + 5%
-can use as first operator, e.g.
5! + 2, or 5% + 20

-Mod operator can not be mixed with other operators.
-Mod usage: to compute 34 mod 5, e.g.
tap 3 4, tap Mod, tap 5, tap =, result: 34 Mod 5 = 4.
