Floating Point Library In WML

    Floating Point Library

The Float library contains a set of math functions.

WMLScript Float Library Functions

The Float library works only on clients that support floating-point numbers. If floating-point numbers are not supported, all functions should return invalid.

Function	Description
ceil(x)	Returns the nearest integer that is not smaller than a specified number
floor(x)	Returns the nearest integer that is not larger than a specified number
int(x)	Returns the integer part of a specified number
maxFloat()	Returns the largest possible floating-point number
minFloat()	Returns the smallest possible floating-point number
pow(x,y)	Returns the value of x raised to the power of y
round(x)	Rounds a number to the nearest integer
sqrt(x)	Returns the square root of a number

1)        WMLScript ceil() Function

The ceil() function returns the nearest integer that is not smaller than the x parameter value.

Syntax

n = Float.ceil(x)

Part	Description
n	The integer returned from the function
x	A number

Example

var a = Float.ceil(5.32); var b = Float.ceil(5.55); var c = Float.ceil(-5.32);

Result

a = 6 b = 6 c = -5

2)        WMLScript floor() Function

The floor() function returns the nearest integer that is not larger than the x parameter.

Syntax

n = Float.floor(x)

Part	Description
n	The integer returned from the function
x	A number

Example

var a = Float.floor(5.32); var b = Float.floor(-5.32);

Result

a = 5 b = -6

3)        WMLScript int() Function

The int() function returns the integer part of the x parameter.

Syntax

n = Float.int(x)

Part	Description
N	The integer returned from the function
X	A number

Example

var a = Float.int(5.32);

Result

a = 5

4)        WMLScript maxFloat() Function

The maxFloat() function returns the largest possible floating-point number.

Syntax

n = Float.maxFloat()

Part	Description
n	The largest possible floating-point number (3.40282347E+38) returned from the function

Example

var a = Float.maxFloat();

Result

a = 3.40282347E+38

5)        WMLScript minFloat() Function

The minFloat() function returns the smallest possible floating-point number.

Syntax

n = Float.minFloat()

Part	Description
n	The smallest floating-point number (1.17549435-38) returned from the function

Example

var a = Float.minFloat();

Result

a = 1.17549435-38

6)        WMLScript pow() Function

The pow() function returns the value of x to the power of y (x^y).

Syntax

n = Float.pow(x,y)

Part	Description
n	The floating-point number returned from the function
x	A number
y	A number

Example

var a = Float.pow(4,2); var b = Float.pow(-2,3);

Result

a = 16 b = -8

7)        WMLScript round() Function

The round() function rounds the x parameter to the nearest integer.

Syntax

n = Float.round(x)

Part	Description
n	The integer returned from the function
x	A number

Example

var a = Float.round(3.5); var b = Float.round(3.4);

Result

a = 4 b = 3

8)        WMLScript sqrt() Function

The sqrt() function returns the square root of the x parameter.

Syntax

n = Float.sqrt(x)

Part	Description
n	The floating-point number returned from the function
x	A number

Example

var a = Float.sqrt(9); var b = Float.sqrt(6.25);

Result

a = 3 b = 2.5
