A **FixedNumber** is a fixed-width (in bits) number with an internal base-10 divisor, which allows it to represent a decimal fractional component.

The FixedNumber constructor cannot be called directly. There are several static methods for creating a FixedNumber.

Returns an instance of a **FixedNumber** for *value* as a *format*.

Returns an instance of a **FixedNumber** for *value* as a *format*.

Returns an instance of a **FixedNumber** for *value* as a *format*. The *value* must not contain more decimals than the *format* permits.

Returns an instance of a **FixedNumber** for *value* with *decimals* as a *format*.

The FixedFormat of *fixednumber*.

Returns a new FixedNumber with the value of *fixedvalue* **+** *otherValue*.

Returns a new FixedNumber with the value of *fixedvalue* **-** *otherValue*.

Returns a new FixedNumber with the value of *fixedvalue* **×** *otherValue*.

Returns a new FixedNumber with the value of *fixedvalue* **÷** *otherValue*.

Returns a new FixedNumber with the value of *fixedvalue* rounded to *decimals*.

Returns true if and only if the value of *FixedNumber* is zero.

Returns a new FixedNumber with the value of *fixedvalue* with *format*.

Returns a string representation of *fixednumber*.

Returns a floating-point JavaScript number value of *fixednumber*. Due to rounding in JavaScript numbers, the value is only approximate.

Returns true if and only if *value* is a **FixedNumber**.

A **FixedFormat** is a simple object which represents a decimal (base-10) Fixed-Point data representation. Usually using this class directly is unnecessary, as passing in a Format Strings directly into the FixedNumber will automatically create this.

A format string is composed of three components, including signed-ness, bit-width and number of decimals.

A signed format string begins with `fixed`

, which an unsigned format string begins with `ufixed`

, followed by the width (in bits) and the number of decimals.

The width must be congruent to 0 mod 8 (i.e. `(width % 8) == 0`

) and no larger than 256 bits and the number of decimals must be no larger than 80.

For example:

**fixed128x18**is signed, 128 bits wide and has 18 decimals; this is useful for most purposes**fixed32x0**is signed, 32 bits wide and has 0 decimals; this would be the same as a`int32_t`

in C**ufixed32x0**is unsigned, 32 bits wide and has 0 decimals; this would be the same as a`uint32_t`

in C**fixed**is shorthand for`fixed128x18`

**ufixed**is shorthand for`ufixed128x18`

Returns a new instance of a **FixedFormat** defined by *value*. Any valid Format Strings may be passed in as well as any object which has any of `signed`

, `width`

and `decimals`

defined, including a FixedFormat object.

The signed-ness of *fixedFormat*, true if negative values are supported.

The width (in bits) of *fixedFormat*.

The number of decimal points of *fixedFormat*.

The name of the *fixedFormat*, which can be used to recreate the format and is the string that the Solidity language uses to represent this format.

*"fixed"*A shorthand for `fixed128x18`
