math Namespace
The math namespace contains the following API elements to help you include common mathematical tasks in your apps.
Functions
The math namespace provides the following functions.
math.floor
This API converts a float value to an integer. The converted integer value is always the integer part of the specified float number (number before the decimal).
Syntax
Math.floor()Return Values
| Return Value | Description |
|---|---|
| integer [Number] | The return value is an integer |
Example
onclickfloor: function(){
var a= this.view.tbxOperations.text;
var b= Math.floor(a);
alert("The converted value is " +b );
},Platform Availability
Available on all platforms.
math.max
This API returns the maximum value among the arguments.
Syntax
Math.max(x,y)Return Values
| Return Value | Description |
|---|---|
| Maximum Value [Number] | The return value is the maximum value among all the arguments |
Example
onclickfloor: function(){
var a= this.view.tbxOperations.text;
var b= Math.floor(a);
alert("The converted value is " +b );
},Platform Availability
Available on all platforms.
math.min
This API returns the minimum value among the arguments.
Syntax
Math.min(x,y,x,...n)Return Values
| Return Value | Description |
|---|---|
| Minimum Value [Number] | The return value is the minimum value among all the arguments |
Example
onclickmin: function(){
var a=this.view.tbxNumber1.text;
var b=this.view.tbxNumber2.text;
var c=Math.min(a,b);
alert("The minimum value is " +c);
},Platform Availability
Available on all platforms.
math.pi
This API returns the value of pi.
Note: math.pi is not a function, but a property in math namespace.
Syntax
Math.PIInput Parameters
None.
Return Values
| Return Value | Description |
|---|---|
| value of pi [Number] | Value of pi is returned |
Example
onclickpi: function(){
var pi= Math.PI;
alert("The pi value is " +pi );
},Platform Availability
Available on all platforms.
math.pow
This API raises the first parameter to the power of the second parameter and returns the result.
Syntax
Math.pow(x,y)Return Values
| Return Value | Description |
|---|---|
| xy | Raises the first parameter to the power of the second parameter |
Implementation Details
It is advisable to use the expression x^y as it is much faster when compared to this API.
Example
onclickpow: function(){
var a= this.view.tbxOperations.text;
var b= Math.pow(a,2);
alert("The Squared value is " +b );
},Platform Availability
Available on all platforms.
math.random
This API generates pseudo-random numbers which are uniformly distributed. This API generates a real number between 0 and 1.
Syntax
Math.random()
Return Values
| Return Value | Description |
|---|---|
| pseudo-random number [Number] | A pseudo-random number between the value 0 and 1 is generated |
Example
onclickRandom: function(){
var random= Math.random();
alert("The random number is " +random);
}Platform Availability
Available on all platforms.
math.sqrt
This API returns the square root of the given number.
Syntax
Math.sqrt()
Return Values
| Return Value | Description |
|---|---|
| square root [Number] | The square root of the number is returned |
| nan (not a number) | This value is returned when the input parameter is a negative number |
Example
onclicksqrt: function(){
var a= this.view.tbxOperations.text;
var b= Math.sqrt(a);
alert("The square root value is " +b );
},Platform Availability
Available on all platforms.
Common Example
var ans = Math.max(10, 20);
var sqrt_num = Math.sqrt(4);
var round_off = Math.floor(2.3);
voltmx.print(Math.PI);
voltmx.print(Math.random);
voltmx.print(Math.pow(2, 3));
voltmx.print(Math.min(10, 20));
