Angles In Radians. Sets iCount to use radians in your trigonometric functions. Angles In Degrees. Sets iCount to use degrees in your trigonometric functions. Iconise Button. Click this button to place iCount on you desktop for fast access. Run Mode. Resets iCount to normal running mode. Function List Mode. Lists all functions you define in the main iCount display. You can then select a function to re-edit or clear from the list. Calculate. Click this button or press the return/enter key to let iCount evaluate your expression. Use this button to save your defined functions. Floating Point. Digit 0. Digit 3. Digit 2. Digit 1. Addition operator +. Example: 4+2. Digit 6. Digit 5. Digit 4. Difference operator -. Also use for the unary sign (-). Example: 4-2+(-1). Digit 9. Digit 8. Digit 7. Multiplication operator *. Example: 4*2. Division operator /. Example: 4/2. Percent operator %. The expression x%y is read as the x percent of y. Example: 50%20. The wastebasket button erases all contents of your edit text. You can also use the top left key of the numeric keypad. Erasing can be undone. NUMBER e. The base of natural logarithms. Short for 2.7182... SYMBOL π. The ratio of the circumference of any circle to its diameter. Short for 3.1415... Close bracket to terminate a clause, or function arguments. Example: 2*(5+√4) Open bracket to type a new clause in your expression, or to enter function arguments. Example: 2*(2+sum(1,2,3)) The symbol '0x' must precede hexadecimal number notation. It should be followed by numbers 0 to 9 and/or letters A to F. Example: 0x1A Use comma to separate arguments in statistical or user defined functions. Example: sum(1,2,3) Root operator √. The expression y√x gives the yth root of x. Ignoring the y component, √x gives the square root of x. Example: 3√9. Power operator ^. The expression x^y is read as: x raised to the power of y. Example: 4^2. Use the '=' symbol when defining a function or constant. #1: hypot=√(ƒ^2+ƒ^2) #2: kb=1024 Maximum 5 letters per name. When done press enter to save. The 'ƒ' symbol lets you define place holders for variables, within user defined functions. Example: vat=17.5%ƒ
