Calculator

The calculator is a powerful tool to do all sorts of calculations and conversions. Type in the entire equation you want to calculate, press equals, and the result is shown:

The calculator operates in three modes:

The software helps you to enter the values or mathematical expressions without syntax errors:


Standard Calculator

The calculator in standard mode allows you to perform standard maths.

Learn descriptions of the functions:

square root Calculates the square root of a value.
x squared Calculates the square of a value.
inverse Calculates the inverse of a value or 1/x.
nth power Calculates the nth power of a value in the format x ^ power.
percent Converts the value to a percent or x/100.
MC Clears the memory.
MR Recalls the memory value indicated by M in the input field.
MS Saves the computed result into memory.
M+ Adds the computed result to the value in memory.
DMS+ Adds the left and right values assuming both are in DMS form.
DMS- Subtracts the right value from the left assuming both are in DMS form.
C Clears all the fields.
<- Backspace, removes the last entered symbol, function name with left parenthesis.
copy If the calculator was started from an edit field, it copies the value back to that field.
sci> Brings up the scientific calculator.
+/- Alternates the last value in the input between positive and negative or appends negative sign to the input.
* Performs multiplication.
/ Performs division.
= Calculates an expression and displays a result
( Sets the left parenthesis.
) Sets the right parenthesis.

Rad Deg Converts radians to degrees.
Deg Rad Converts degrees to radians.
Grad Deg Converts gradians to degrees.
Deg Grad Converts degrees to gradians.
Deg DMS Converts degrees to degrees minutes seconds notation.
DMS Deg Converts degrees minutes seconds notation to degrees.
Rec Pol Converts rectangular coordinates (xy) to polar (r theta). This is done by using both result fields, the top one being x, bottom one being y. Enter the values and click Rec Pol and it will convert the top value to r and bottom to theta.
Pol Rec Converts polar coordinates (r theta) to rectangular (xy). This is done by using both result fields, the top one being r, bottom one being theta. Enter the values and click Pol Rec and it will convert the top value to x and bottom to y.
DMS+ Adds the left and right values assuming both are in DMS form.
DMS- Subtracts the right value from the left assuming both are in DMS form.
e The constant e, base of the natural logarithm.
pi The constant pi, the circumference to diameter ratio for any circle.
C Clears all the fields.
<- Backspace, removes the last entered symbol, function name with left parenthesis.
copy If the calculator was started from an edit field, it copies the value back to that field.
fti> Brings up the Feet/Inches calculator.
Deg If this is showing, it means the calculator is working in degrees.
Grad If this is showing, it means the calculator is working in gradians.
Rad If this is showing, it means the calculator is working in radians.
+/- Alternates the last value in the input between positive and negative or appends negative sign to the input.
* Performs multiplication.
/ Performs division.
= Calculates an expression and displays a result
( Sets the left parenthesis.
) Sets the right parenthesis.

Feet/Inches Calculator

The calculator in feet/inch mode allows you to perform feet and inches calculation.

Learn descriptions of the functions:

FT Sets the Feet mark (') for any entered value. You can use this button once for the value. It is imposable to enter feet sign after inch sign or fractional inch denominator.
IN Sets the Inch mark (") for any entered value. You can use this button once for the value. It is imposable to enter inch sign after fractional inch denominator.
/ Sets the denominator of fractional inch. Select the required value from the list. The entered by user value is the numerator. You can use this button once for the value.
. and space bar

Depending upon the position of the value sets the following:

  • for the value without any mark (same as clicking the FT button): sets the Feet mark (') for any entered value: 7 -> clicking . or space bar -> 7'
  • for the value which entered after Feet (same as clicking the IN button) sets the Inch mark (") for any entered value: 7'5-> clicking . or space bar -> 7'5"
  • for the value which entered after Inch (same as clicking the / button) sets the denominator of fractional inch. Select the required value from the list. The entered by user value is the numerator: 7'5"4 -> clicking . or space bar -> select from the list any fractional ->7'5"4/128
  • for the value in Feet sets the Inch mark ("): 7' -> clicking . or space bar -> 7"
  • for the value in Inch sets the denominator of fractional inch. Select the required value from the list. 7" -> clicking . or space bar -> select from the list any fractional ->7/128
square root Calculates the square root of a value.
x squared Calculates the square of a value.
inverse Calculates the inverse of a value.
nth power Calculates the nth power of a value in the format x ^ power.
percent Converts the value to a percent or x/100.
MC Clears the memory.
MR Recalls the memory value indicated by M in the input field.
MS Saves the computed result into memory.
M+ Adds the computed result to the value in memory.
C Clears all the fields.
<- Backspace, removes the last entered symbol, function name with left parenthesis or fractional inches denominator.
copy If the calculator was started from an edit field, it copies the value back to that field.
std> Brings up the standard calculator.
+/- Alternates the last value in the input between positive and negative or appends negative sign to the input.
* Performs multiplication.
