Numeric.isShort

check if the value stored in the Numeric fits into a Java short

 Calling Sequence boolean isShort() throws MapleException

Description

 • The isShort function returns true if the value represented by the current Numeric object is an integer small enough to fit into a Java short. Otherwise, the isShort function returns  false.
 • If isShort returns true, a call to one of shortValue, intValue or longValue completes without error.

Examples

 import com.maplesoft.openmaple.*; import com.maplesoft.externalcall.MapleException; class Example { public static void main( String notused[] ) throws MapleException { String mapleArgs[]; Engine engine; Numeric n; short s; mapleArgs = new String[1]; mapleArgs[0] = "java"; engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); n = (Numeric)engine.evaluate( "2^18:" ); System.out.println( n.isShort() ); try { n.shortValue(); } catch ( MapleException me ) { System.out.println( me.getMessage() ); } n = (Numeric)engine.evaluate( "2^14:" ); System.out.println( n.isShort() ); s = n.shortValue(); System.out.println( s ); } }

Executing this code produces the following output.

 false Error, value does not fit in integer[2] true 16384
