Method Summary

Modifier and Type	Method and Description
INum	add(INum val)
double	getRealPart()
int	intValue() Returns the value of this number as an int (by simply casting to type int).
boolean	isNumIntValue() Check if this expression represents an int value.
INum	multiply(INum val)
INum	pow(INum val)
int	toInt() Converts this double value to an int value; unlike intValue() this method raises ArithmeticException if this integer cannot be represented by an int type.

Method Detail

getRealPart

double getRealPart()

add

INum add(INum val)

multiply

INum multiply(INum val)

pow

INum pow(INum val)

isNumIntValue

boolean isNumIntValue()

Check if this expression represents an int value. The value of an INum object can be an int value.

Specified by:

isNumIntValue in interface IExpr

Returns:

intValue

int intValue()

Returns the value of this number as an int (by simply casting to type int).

Returns:

toInt

int toInt()
   throws java.lang.ArithmeticException

Converts this double value to an int value; unlike intValue() this method raises ArithmeticException if this integer cannot be represented by an int type.

Specified by:

toInt in interface ISignedNumber

Returns:

the numeric value represented by this integer after conversion to type int.

Throws:

java.lang.ArithmeticException - if conversion to int is not possible.
