(1) Numeric Keypad

You can use this numeric keypad like the one on your keyboard. The "Exp" button allows you to insert values in exponential notation. E.g.: "2.3e2" becomes 230.

 

(2) Basic Math Operations

Basic math operations like addition, subtraction, multiplication or divison are located here.

 

(3) Edit Functions

The "Del" button behaves like the backspace or delete key on your keyboard. If there are characters right from the cursor it first deletes these. If there are none it deletes the characters on the left side.

 

(4) View The Result

Pressing this button calculates the result of the term entered in the (13) Term Edit Box and displays it in in (14) Result Box. If an error occures while calculating the term's result, the specific error code is displayed instead of a result. See also Error Codes.

 

(5) Insert The Ans Variable

If you want to use the result of the previous calculation in your current term you haven't to copy and paste it. You can just insert the Ans variable by pressing this key. The Ans variable always contains the latest calculation result.

 

(6) Brackets

This buttons insert brackets in your term.

 

 

(7) Scientific Functions

 

x^(1/y)

This function is similar to the normal root funtion. The 'x' specifies the radikand and 'y' the grade of the root.
E.g.: if you want to calculate you just type "8^(1/3)".

 

x^(-1)

Calculates the reciprocal of the value 'x'. E.g.: "2^(-1) = 0.5".

 

x^y

Calculates 'x' raised by 'y'. E.g.: "2^3 = 8".

 

x^2

Calculates the square of 'x'. E.g.: "3^2 = 9".

 

x^3

Calculates the cubic of 'x'. E.g.: "2^3 = 9".

 

log

Calculates the logarithm of a value based to 10. E.g.: "log(100) = 2".

 

sin

Calculates the sine of a value. E.g.: "sin(90) = 1"
Info: This function depends on the angle mode settings.

 

cos

Calculates the cosine of a value. E.g.: "cos(90) = 0".
Info: This function depends on the angle mode settings.

 

tan

Calculates the tangent of a value. E.g.: "tan(45) = 1".
Info: This function depends on the angle mode settings.

 

asin

Calculates the arcsine of a value. E.g.: "asin(1) = 90"
Info: This function depends on the angle mode settings.

 

acos

Calculates the arccosine of a value. E.g.: "acos(0) = 90".
Info: This function depends on the angle mode settings.

 

atan

Calculates the arctangent of a value. E.g.: "atan(1) = 45".
Info: This function depends on the angle mode settings.

 

sgn

The signum function returns "-1" for all negative values, "1" for all positive values and "0" when entering "0".
E.g.: "sgn(-234) = -1", "sgn(47) = 1", "sgn(0) = 0"

 

abs

Calculates the absolute value. E.g.: "abs(-34) = 34", "abs(25) = 25".

 

 

(8) The Variables Manager

Miichsoft SciCal supports to store values in variables and later to recall them later. You can store a value by pressing "Sto". A variable can be recalled with the "Use" button. For more information read the Variables Manager description.

 

(9) Angle Modes

The calculator supports three angle modes. These affect all trigonometric functions.

Mode Description Example
Deg Degree 90°
Rad Radian π/2
Gra Grade 100

 

(10) Fraction Conversion

Pressing this button converts the decimal result displayed in (14) Result Box into a fraction. E.g.: "1.25" becomes "5 / 4". If the value cannot be converted, nothing happens.

 

(11) Change View Mode

This button opens a menu where you can select how the results are to be displayed in the (14) Result Box. You can choose from the following:

Mode Description Meaning of the value Example Value Example Output
Norm normal decimal numbers maximum digits to print 5 52.635
Sci scientific mode number of valid digits 2 5.3e1
Fix fixed decimal digits digits behind the decimal point 1 52.6

 

(12) History

This button opens a menu where you can see all terms and their results entered earlier. By selecting an element in the list, the specific term is recalled and is displayed in the (13) Term Edit Box. The term's result is automatically been displayed in the (14) Result Box. The number of terms stored in the history is limited to 10. When the list is full, the oldest elements are overwritten.

 

(13) Term Edit Box

The term you want to calculate is entered here.

 

(14) Result Box

A term's result is displayed here, after pressing the (4) View The Result button. If an error occures the specific error code is displayed instead of the result.

 

2. The Variables Manager

1. Storing Values

To store a value in a variable for later use first press the "Sto" button in the calculator window. This brings up the Variables Manager which is shown above. Now enter a name for the new variable or enter the name of an existing variable. If you do so, a new value will be attached to the existing variable. The Value Box should already contain the result of the last calculation. If you want to store another value just enter it here. When you have entered all needed information just press "Store" and your variable is available.
Info: Some variables may have a 'C' before the value. That means they are constant and cannot be overwritten with a new value.

 

2. Recalling Variables

To use a variable click on the "Use" button in the SciCal main window. This will exactly as "Sto", bring up the Variables Manager with the difference that now the "Name" and "Value" fields are disabled cause you don't need them. To recall a variable just select it in the list and then press "Use". The Variable will be inserted on the current cursor pos.

 

3. Error Codes

The meaning of the calculator's error messages are listed here:
