byte byteValue() throws MapleException
|
|
|
Description
|
|
|
•
|
The byteValue function returns the value represented in the Numeric as a Java byte. If the value does not fit exactly into a Java byte, an error is raised.
|
|
•
|
To determine if the value fits within a Java byte, use the isByte function.

class Example
|
|
{
|
|
public static void main( String notused[] ) throws MapleException
|
|
{
|
|
String mapleArgs[];
|
|
Engine engine;
|
|
Numeric n;
|
|
byte b;
|
|
mapleArgs = new String[1];
|
|
mapleArgs[0] = "java";
|
|
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
|
|
null, null );
|
|
n = (Numeric)engine.evaluate( "200:" );
|
|
System.out.println( n.isByte() );
|
|
try
|
|
{
|
|
n.byteValue();
|
|
}
|
|
catch ( MapleException me )
|
|
{
|
|
System.out.println( me.getMessage() );
|
|
}
|
|
n = (Numeric)engine.evaluate( "100:" );
|
|
System.out.println( n.isByte() );
|
|
b = n.byteValue();
|
|
System.out.println( b );
|
|
}
|
|
}
