### Math Operations
|
||
|
|
||
|
#### *fixednumber* . **addUnsafe**( otherValue ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* **+** *otherValue*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **subUnsafe**( otherValue ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* **-** *otherValue*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **mulUnsafe**( otherValue ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* **\*** *otherValue*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **divUnsafe**( otherValue ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* **/** *otherValue*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **round**( [ decimals = 0 ] ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* rounded to *decimals*.
|
||
|
|
||
|
|
||
|
### Conversion
|
||
|
|
||
|
#### *fixednumber* . **toFormat**( format ) => *[FixedNumber](/v5/api/utils/fixednumber/)*
|
||
|
|
||
|
Returns a new FixedNumber with the value of *fixedvalue* with *format*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **toHexString**( ) => *string*
|
||
|
|
||
|
Returns a [HexString](/v5/api/utils/bytes/#HexString) representation of *fixednumber*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **toString**( ) => *string*
|
||
|
|
||
|
Returns a string representation of *fixednumber*.
|
||
|
|
||
|
|
||
|
#### *fixednumber* . **toUnsafeFloat**( ) => *float*
|
||
|
|
||
|
Returns a floating-point JavaScript number value of *fixednumber*. Due to rounding in JavaScript numbers, the value is only approximate.
|
||
|
|
||
|
|
||
|
### Inspection
|
||
|
|
||
|
#### *FixedNumber* . **isFixedNumber**( value ) => *boolean*
|
||
|
|
||
|
Returns true if and only if *value* is a **FixedNumber**.
