All Implemented Interfaces:

java.io.Serializable

public class MFloat
extends java.lang.Number

This class is a wrapper for float values and is similar to the existing Java wrapper class Float?. However, unlike the Float class, MFloat is mutable, allowing you to change the float value that it wraps.

Constructor Detail

MFloat

public MFloat(float num)

Constructs an MFloat object and sets it to the specified float value.

Parameters:

num - A float specifying the value to which you want the new MFloat object set.

MFloat

public MFloat(java.lang.String s)
       throws java.lang.NumberFormatException

Constructs an MFloat object and sets it according to the value specified in the String parameter, s. (The Float object's valueOf method is used to convert the string to a numeric value.)

Parameters:

s - A String specifying the value to which you want the new MFloat object set.

Throws:

java.lang.NumberFormatException - if s does not contain a String that can be successfully converted to a float value.

Method Detail

setValue

public void setValue(float num)

Sets this MFloat object to the specified float value.

Parameters:

num - A float specifying the value to which you want this MFloat object set.

public float getValue()

Returns the value of this MFloat object as a float.

Returns:

A float that has the numeric value represented by this MFloat object.

toString

public java.lang.String toString()

Returns a String representation of this MFloat object's value. (The Float object's toString method is used to convert the object's value to a String.)
