* An integer, 0 to 1e+9, or an array, [-1e+9 to 0, 0 to 1e+9].
* Default value: `[-7, 20]`.
*
* The exponent value(s) at which `toString` returns exponential notation.
*
* If a single number is assigned, the value is the exponent magnitude.
*
* If an array of two numbers is assigned then the first number is the negative exponent value at
* and beneath which exponential notation is used, and the second number is the positive exponent
* value at and above which exponential notation is used.
*
* For example, to emulate JavaScript numbers in terms of the exponent values at which they begin
* to use exponential notation, use `[-7, 20]`.
*
* ```ts
* BigNumber.config({ EXPONENTIAL_AT: 2 })
* new BigNumber(12.3) // '12.3' e is only 1
* new BigNumber(123) // '1.23e+2'
* new BigNumber(0.123) // '0.123' e is only -1
* new BigNumber(0.0123) // '1.23e-2'
*
* BigNumber.config({ EXPONENTIAL_AT: [-7, 20] })
* new BigNumber(123456789) // '123456789' e is only 8

*
* // Almost never return exponential notation:
* BigNumber.config({ EXPONENTIAL_AT: 1e+9 })
*
* // Always return exponential notation:
* BigNumber.config({ EXPONENTIAL_AT: 0 })
* ```
*
* Regardless of the value of `EXPONENTIAL_AT`, the `toFixed` method will always return a value in
* normal notation and the `toExponential` method will always return a value in exponential form.
* Calling `toString` with a base argument, e.g. `toString(10)`, will also always return normal
* notation.

*
* If a single number is assigned, it is the maximum exponent magnitude: values wth a positive
* exponent of greater magnitude become Infinity and those with a negative exponent of greater
* magnitude become zero.
*
* If an array of two numbers is assigned then the first number is the negative exponent limit and
* the second number is the positive exponent limit.
*
* For example, to emulate JavaScript numbers in terms of the exponent values at which they
* become zero and Infinity, use [-324, 308].
*
* ```ts
* BigNumber.config({ RANGE: 500 })
* BigNumber.config().RANGE // [ -500, 500 ]

* new BigNumber(0.001) // '0.01' e is only -3
* new BigNumber(0.0001) // '0' e is -4

* `EUCLID` | 9 | The remainder is always positive.

* x = new BigNumber(123.4567) // '123.4567'
* // 'new' is optional
* y = BigNumber(x) // '123.4567'
* ```
*
* If `n` is a base 10 value it can be in normal (fixed-point) or exponential notation.
* Values in other bases must be in normal notation. Values in any base can have fraction digits,
* i.e. digits after the decimal point.
*
* ```ts
* new BigNumber(43210) // '43210'
* new BigNumber('4.321e+4') // '43210'
* new BigNumber('-735.0918e-430') // '-7.350918e-428'
* new BigNumber('123412421.234324', 5) // '607236.557696'

* new BigNumber('-Infinity') // '-Infinity'
* new BigNumber(NaN) // 'NaN'
* new BigNumber(-0) // '0'
* new BigNumber('.5') // '0.5'
* new BigNumber('+2') // '2'
* ```
*
* String values in hexadecimal literal form, e.g. `'0xff'`, are valid, as are string values with
* the octal and binary prefixs `'0o'` and `'0b'`. String values in octal literal form without the
* prefix will be interpreted as decimals, e.g. `'011'` is interpreted as 11, not 9.
*
* ```ts
* new BigNumber(-10110100.1, 2) // '-180.5'
* new BigNumber('-0b10110100.1') // '-180.5'
* new BigNumber('ff.8', 16) // '255.5'
* new BigNumber('0xff.8') // '255.5'
* ```
*
* If a base is specified, `n` is rounded according to the current `DECIMAL_PLACES` and
* `ROUNDING_MODE` settings. This includes base 10, so don't include a `base` parameter for decimal
* values unless this behaviour is desired.
*
* ```ts
* BigNumber.config({ DECIMAL_PLACES: 5 })
* new BigNumber(1.23456789) // '1.23456789'
* new BigNumber(1.23456789, 10) // '1.23457'
* ```
*
* An error is thrown if `base` is invalid.
*
* There is no limit to the number of digits of a value of type string (other than that of
* JavaScript's maximum array size). See `RANGE` to set the maximum and minimum possible exponent
* value of a BigNumber.
*
* ```ts
* new BigNumber('5032485723458348569331745.33434346346912144534543')
* new BigNumber('4.321e10000000')
* ```
*
* BigNumber `NaN` is returned if `n` is invalid (unless `BigNumber.DEBUG` is `true`, see below).
*
* ```ts
* new BigNumber('.1*') // 'NaN'
* new BigNumber('blurgh') // 'NaN'
* new BigNumber(9, 2) // 'NaN'
* ```
*
* To aid in debugging, if `BigNumber.DEBUG` is `true` then an error will be thrown on an
* invalid `n`. An error will also be thrown if `n` is of type number with more than 15
* significant digits, as calling `toString` or `valueOf` on these numbers may not result in the
* intended value.
*
* ```ts
* console.log(823456789123456.3) // 823456789123456.2
* new BigNumber(823456789123456.3) // '823456789123456.2'
* BigNumber.DEBUG = true

* new BigNumber(823456789123456.3)
* // 'Error: Not a base 2 number'
* new BigNumber(9, 2)
* ```
*
* A BigNumber can also be created from an object literal.
* Use `isBigNumber` to check that it is well-formed.
*
* ```ts
* new BigNumber({ s: 1, e: 2, c: [ 777, 12300000000000 ], _isBigNumber: true }) // '777.123'
