public static final Integer64 ZERO

The 64 bits floating point representing zero.

ONE

public static final Integer64 ONE

The 64 bits floating point representing one.

Method Detail

valueOf

public static Integer64 valueOf(long longValue)

Returns the 64 bits integer from the specified long value.

Parameters:

longValue - the long value for this number.

Returns:

the corresponding number.

minus

public Integer64 minus(Integer64 that)

Returns the difference between this number and the one specified.

Overrides:

minus in class Number<Integer64>

Parameters:

that - the number to be subtracted.

Returns:

this - that.

times

public Integer64 times(Integer64 that)

Returns the product of this number with the one specified.

Parameters:

that - the number multiplier.

Returns:

this · that.

divide

public Integer64 divide(Integer64 that)

Returns this number divided by the one specified.

Parameters:

that - the number divisor.

Returns:

this / that.

isLargerThan

public boolean isLargerThan(Integer64 that)

Compares the magnitude of this number with that number.

Specified by:

isLargerThan in class Number<Integer64>

Returns:

|this| > |that|

Compares this number against the specified object.

Specified by:

equals in class Number<Integer64>

Parameters:

that - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

hashCode
