Class Long

Longs are positive and negative whole 64-bit unsigned numbers without decimals. If you need to work with decimals, use the Float data type. To represent a long number in the code as a literal, suffix it with an "L", for example, "Long l = 576460752303423488L;"

Constructors

Long()

Default constructor.

Declaration

Long Long()

Type	Description
Long

Long(Integer)

Pass a value to copy into a new object.

Declaration

Long Long(Long value)

Parameters

Type	Name	Description
Long	value	Long object.

Type	Description

Methods

toString()

Converts a numeric value to its string representation.

One of the most frequently used methods, typically when you are going to output something.

Declaration

String toString()

Examples

Long c = 576460752303423488L;
String s = c.toString();

Returns

Type	Description
String

isNull()

Returns true if it has no value and false if it does.

Declaration

Bool isNull()

Examples

Long i;
printLine(i.isNull().toString());
i = 0;
printLine(i.isNull().toString());

The first output will be true because we haven't initialized i yet. The next output will be false because i now has the value 0.

Returns

Type	Description
Bool

getHighInteger()

Returns the high 32-bit Integer of the Long.

Declaration

Integer getHighInteger()

Examples

Long c = 576460752303423488L;
print(c.getHighInteger().toString());

Returns

Type	Description
Integer

getLowInteger()

Returns the low 32-bit Integer of the Long.

Declaration

Integer getLowInteger()

Examples

Long c = 576460752303423488L;
print(c.getLowInteger().toString());

Returns

Type	Description
Integer
