Summary
Calcpad - cool calculator is a simple mathematical formula calculator.You can define your own constants and functions. In addition to handlingfloating point arithmetic, CalcPad takes care of your big-decimal arithmeticneeds as well. Plus, you can stop fighting with your on-screen keyboardand opt for the Text-to-speech(TTS) function to kick off your calculations.

About CalcPad
CalcPad is a simple mathematical formula calculator.
In addition to standard function calculator, define your own constantsand functions the user can extend the functionality.
In addition to the double-precision floating point arithmetic, arbitrary-precisiondecimal (Big decimal) arithmetic (you can specify the number of decimalplaces) can be.
The result and formula can be audio output by Text-to-speech(TTS).
For small devices, voice input function formula, select completions, and features the history of input and gesture input.
Writing Formulas
Formula is the same as normal. Numbers, operators, use parentheses.
The last result is stored as a constant 'ans'.
Examples
1+2*3/4+5^(6/7)
ans*2
Blank
Number of expressions, operators, space contained between the parenthesesare ignored.
Operators
- + Addition(Weak)
- - Subtraction(Weak)
- * Multiplication(Strong)
- / Division(Strong)
- ^ Power(Strong)
Priorities are as arithmetic operators. When you join without parenthesesstrong operator and weak operators are arithmetic operators stronger thanbefore.
Comment
String('//') is treated as a comment. Description of constantsand functions can be used.
User defined constants
A number often used 'user-defined constant' can be named as.
'Constant name' = 'formula' represented.
Examples
c=2.99792458e-8
User defined functions
The User defined function can be described as 'function name' = 'formula'.
The arguments in written expression: $0 - $9. The first argument is $0.
Examples
LengthCircle=2*PI*$0 // Circumference
AreaCircle=PI*($0^2) // Area of a circle
Dice=floor(1+random($0)) // Dice(1-6)
Fib=floor(1/sqrt(5)*(((1+sqrt(5))/2)^$0-((1-sqrt(5))/2)^$0)) // Fibonaccinumber

Pre-defined constants
The following constants are built in advance. In the formula can be writtenas a number.
PI = 3.141592653589793
1x0=
E = 2.718281828459045
DeciamlPrecision constant
DecimalPrecision is zero or more, and arbitrary-precision big decimal calculations,the number of decimal places represented DecimalPrecision.
The negative value less than zero, do the usual floating-point calculations(default)
Examples
DecimalPrecision=-1 // Double-precision floating-point calculations10000000000000000-1
ans=1.0e16
DecimalPrecision=1 //big decimal calculation
10000000000000000-1
ans=999999999999999
Speech Constant
Speech constant is controls of the audio output.
Speech=0
- 0 : Disable audio output (default)
- 1 : Only result
- 2 : Only formula
- 3 : formula and result
- 4 : Only define formula
- 7 : All
TextSize Constant
TextSize changes size of the Text
Example
TextSize=120.0
OutputVisibility Constant
OutputVisibility specifies the output display area.
OutputVisibility=0 : Visible
OutputVisibility=1 : Invisible

Text-To-Speech
Text-To-Speech (TTS). Also known as 'speech synthesis', TTS enablesyour Android device to 'speak' text of your language.
If TTS is not supported in your language, CalcPad trys to speak in English.
Voice Recognition
Speech input adds another dimension to staying in touch. Because CalcPad use Google's Voice Search Engine, formula representation is insufficient. For example, '*' is not'multiply', but 'asterisk' and '/' is not 'divide', but 'slash'.
If Speech Input is not supported in your language, CalcPad trys to recognizein English.
Gestures Input
Touch screens are a great way to interact with applications on mobile devices.With a touch screen, users can easily tap, drag, fling, or slide to quickly perform actions in CalcPad. If gesturefile('gestures') exists in SD-card, CalcPad uses external gesturefile. This means that you can customize gesture as you like.
Pre-defined gestures
Gesture Commands
- enter : 'enter' or 'return'
- bs : BackSpace
- clear : clear edit box
- copy : copy to the clipboard
- paste : paste from the clipboard
