【實用工具app】Smart Student Calculator free|最夯免費app

KCalculator provides following features:

- Arithmetic operations like multiplication, addition, division and etc.

- Trigonometric functions calculation. (sin, cos, tan , asin, acos, atan) Important: it is assumed that data entered in not radians but degrees.

- Full memory manipulations support: add to memory, subtract, store to and fetch data out of memory. Clean memory up.

- Percentages calculation.

- Multiline formula support

- Correct result calculation despite on input complexity. KCalc understands the priority of mathematical operations and strickly following them.

Example: 2+2*(3*3)= 20

- Full stop separation number support

- Factorial calculation

- E and PI constants values stored in the memory

- Brackets support

- Squareroot and power support

- Log and ln logorithm values calculation

- Shows up warning and errors that can be made by user during his work (Example: 1/0 gives you an error since it is prohibited)

FAQ

Extra functionality are available on additional panel. To open it up please press -> , to return press <-

M+ add value to one in memory

M- substract value from one in memory

MS replace value in memory by current one

MR fetch result out of memory

MC set value in memory to 0

n! calculate factorial - 5n! = 5*4*3*2*1=120

sin, cos and tan calculation for radians, degrees and grads

asin, acos, atan caluclates angle (degrees, grads or radians) from value

log(value) calculates logorithm of value (base of 2)

log(8) = 3

ln(value) calculates logorithm of value (base of e)

e - constant 2,7182818284590452353602874713527

pi - constant 3,1415926535897932384626433832795

% - 100+10% = 110

del - remove last entered digit 55del -> 5

CE - set input to 0, 2+55CE -> 2+0

C - erase all data

( - open bracket, used for priority, 2/(1+1) = 1

) - close bracket

Error information system will inform you if any of your actions are not permitted and lead to arithmetic error

For example: 1/0 leads to the following notification:

error (y/x; x should not be 0)

Memory usage indicator: at the top of the screen you might find a green character M, which indicates that memory holds a value, which may be accessed. If indicator is off(visible), then it is empty.

Currently selected angle type indicator, keeps you informed about angle measure you are currently using on.
