Class BigInt
BigInt
A BigInt object is a wrapper for a primitive
bigint value.
bigint values can be numbers too large to be stored as number values.
A bigint literal in code is an integer number with an appended n.
Example:
var hugeNumber = 1245678901234567890n;
var hugeNumberObject = BigInt( hugeNumber );
API Versioned:
From version 22.7.

Constructor Detail
BigInt
public BigInt(value
:
BigInt)
Constructs a new BigInt using the specified BigInt.
Parameters:
value
-
the BigInt to use.
BigInt
public BigInt(value
:
String)
Constructs a BigInt using the specified value.
Beside decimal numbers also binary, octal and hexadecimal numbers are supported:
var decimal = BigInt( "12" );
var binary = BigInt( "0b1100" );
var octal = BigInt( "0o14" );
var hex = BigInt( "0xC" );
Parameters:
value
-
the value to use when creating the BigInt.
Method Detail
asIntN
Clamps the given BigInt value to a signed integer with a given precision.
Parameters:
bits
-
Number of bits required for resulting integer.
value
-
The value to be clamped to the given number of bits.
Returns:
The
value modulo 2bits, as a signed integer.
asUintN
Clamps the given BigInt value to an unsigned integer with a given precision.
Parameters:
bits
-
Number of bits required for resulting integer.
value
-
The value to be clamped to the given number of bits.
Returns:
The
value modulo 2bits, as an unsigned integer.
