Constructor	Type	Description
new Hbar(<amount>)	Hbar	Initializes the Hbar object

new Hbar(<amount>)

HBAR from:

Construct HBAR from different representations.

Method	Type	Description
Hbar.from(<hbars>)	long / BigDecimal	Returns an Hbar whose value is equal to the specified value
Hbar.from(<hbars, unit>)	long / BigDecimal , HbarUnit	Returns an Hbar representing the value in the given units
Hbar.fromString(<text>)	CharSequence	Converts the provided string into an amount of hbars
Hbar.fromString(<text, unit>)	CharSequence, HbarUnit	Converts the provided string into an amount of hbars
Hbar.fromTinybars(<tinybars>)	long	Returns an Hbar converted from the specified number of tinybars

Java

//100 HBAR
new Hbar(100);

//100 HBAR from hbar value
Hbar.from(100);

//100 tinybars from HBAR convert to unit
Hbar.from(100, HbarUnit.TINYBAR);

// 100 HBAR converted from string value
Hbar.fromString("100");

//100 tinybars from string value
Hbar.fromString("100", HbarUnit.TINYBAR);

HBAR to:

Convert HBAR to a different unit/format.

Method	Type	Description
to(<unit>)	HbarUnit	Specify the unit of hbar to convert to. Use As for Go.
toString(<unit>)	HbarUnit	String value of the hbar unit to convert to. Use String() for Go.
toTinybars()	Long	Hbar value converted to tinybars

Java

//100 HBAR converted to tinybars
new Hbar(100).to(HbarUnit.TINYBAR);

//100 HBAR converted to tinybars

HBAR constants:

Provided constant values of HBAR.

Method	Type	Description
Hbar.MAX	Hbar	A constant value of the maximum number of hbars (50_000_000_000 hbars)
Hbar.MIN	Hbar	A constant value of the minimum number of hbars (-50_000_000_000 hbars)
Hbar.ZERO	Hbar	A constant value of zero hbars

Java

//The maximum number of hbars
Hbar hbarMax = Hbar.MAX; 

//The minimum number of hbars
Hbar hbarMin = Hbar.MIN;

//A constant value of zero hbars
Hbar hbarZero = Hbar.ZERO;

HBAR units

Modify the HBAR representation to one of the HBAR denominations.

Function	Description
HbarUnit.TINYBAR	The atomic (smallest) unit of hbar, used natively by the Hedera network
HbarUnit.MICROBAR	Equivalent to 100 tinybar or 1⁄1,000,000 hbar.
HbarUnit.MILLIBAR	Equivalent to 100,000 tinybar or 1⁄1,000 hbar
HbarUnit.HBAR	The base unit of hbar, equivalent to 100 million tinybar.
HbarUnit.KILOBAR	Equivalent to 1 thousand hbar or 100 billion tinybar.HbarUnit.Megabar
HbarUnit.MEGABAR	Equivalent to 1 million hbar or 100 trillion tinybar.
HbarUnit.GIGABAR	Equivalent to 1 billion hbar or 100 quadrillion tinybar.

Java

//100 tinybars
Hbar.from(100, HbarUnit.TINYBAR);

HBAR decimal places

The decimal precision of HBAR varies across the different Hedera APIs, with HAPI, JSON-RPC Relay, and Hedera Smart Contract Service (EVM) returning 8 decimal places, while JSON-RPC Relay msg.value returns 18 decimal places.

API	Decimal
Hedera API (HAPI) (Crypto + SCS Service (msg.value))	8
Hedera Smart Contract Service (EVM)	8
JSON RPC Relay (passed as arguments)	8
JSON RPC Relay (msg.value)	18

Note: The JSON-RPC Relay msg.value uses 18 decimals when it returns HBAR. As a result, the gasPrice also uses 18 decimal places since it is only utilized from the JSON-RPC Relay.
