####5.0.0
* 25/01/2016
* Added trigonometric functions and `cubeRoot` method.
* Added most of JavaScript's `Math` object methods as Decimal methods.
* Added `toBinary`, `toHexadecimal` and `toOctal` methods.
* Added `isPositive` method.
* Removed the 15 significant digit limit for numbers.
* String values containing whitespace or a plus sign are no longer accepted.
* `valueOf` now returns `'-0'` for minus zero.
* `comparedTo` now returns `NaN` not `null` for comparisons with `NaN`.
* `Decimal.max` and `Decimal.min` no longer accept an array.
* The Decimal constructor and `toString` no longer accept a base argument.
* Binary, hexadecimal and octal prefixes are now recognised for string values.
* Removed `Decimal.errors` configuration property.
* Removed `toFormat`.
* Removed `Decimal.ONE`.
* Renamed `exponential` method to `naturalExponential`.
* Renamed `Decimal.constructor` method to `Decimal.clone`.
* Simplified error handling and amended error messages.
* Refactored the test suite.
* `Decimal.crypto` is now `undefined` by default, and the `crypto` object will be used if available.
* Major internal refactoring.
* Removed *bower.json*.
####4.0.2
* 20/02/2015 Add bower.json. Add source map. Amend travis CI. Amend doc/comments.
####4.0.1
* 11/12/2014 Assign correct constructor when duplicating a Decimal.
####4.0.0
* 10/11/2014 `toFormat` amended to use `Decimal.format` object for more flexible configuration.
####3.0.1
* 8/06/2014 Surround crypto require in try catch. See issue #5
####3.0.0
* 4/06/2014 `random` simplified. Major internal changes mean the properties of a Decimal must now be considered read-only
####2.1.0
* 4/06/2014 Amend UMD
####2.0.3
* 8/05/2014 Fix NaN toNumber
####2.0.2
* 30/04/2014 Correct doc links
####2.0.1

## Features
- Integers and floats
- Simple but full-featured API
- Replicates many of the methods of JavaScript's `Number.prototype` and `Math` objects
- Also handles hexadecimal, binary and octal values
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
- Simple API but full-featured
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
- Includes a `toFraction` and correctly-rounded `exp`, `ln`, `log` and `sqrt` functions
- Supports non-integer powers
- Works with numbers with or without fraction digits in bases from 2 to 64 inclusive
- No dependencies
- Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
- Comprehensive [documentation](http://mikemcl.github.io/decimal.js/) and test set

15.8.2.13 pow (x, y)
Returns an implementation-dependent approximation to the result of raising x to the power y.
If y is NaN, the result is NaN.
If y is +0, the result is 1, even if x is NaN.
If y is -0, the result is 1, even if x is NaN.
If x is NaN and y is nonzero, the result is NaN.
If abs(x)>1 and y is +Infinity, the result is +Infinity.
If abs(x)>1 and y is -Infinity, the result is +0.
If abs(x)==1 and y is +Infinity, the result is NaN.
If abs(x)==1 and y is -Infinity, the result is NaN.
If abs(x)<1 and y is +Infinity, the result is +0.
If abs(x)<1 and y is -Infinity, the result is +Infinity.
If x is +Infinity and y>0, the result is +Infinity.
If x is +Infinity and y<0, the result is +0.
If x is -Infinity and y>0 and y is an odd integer, the result is -Infinity.
If x is -Infinity and y>0 and y is not an odd integer, the result is +Infinity.
If x is -Infinity and y<0 and y is an odd integer, the result is -0.
If x is -Infinity and y<0 and y is not an odd integer, the result is +0.
If x is +0 and y>0, the result is +0.
If x is +0 and y<0, the result is +Infinity.
If x is -0 and y>0 and y is an odd integer, the result is -0.

For help:

Usage example:
Compare the time taken by the Decimal plus method and the BigDecimal add method.
Time 10000 calls to each.
Use operands of up to 40 random digits (each unique for each iteration).
Check that the Decimal results match the BigDecimal results.

// Rounds operands to precision before performing a calculation.
// Rounding to precision of add, subtract and pow seems unfathomable/unreliable, but it
// matches the java version, see <http://speleotrove.com/decimal/dax3274.html>.
// Pass a MathContext object to an arithmetic operation to set a precision/rounding mode.
// Pass integers to set the scale (i.e. dp) and rounding mode for divide only.
// (Passing one integer to divide sets the rounding mode.)
// Default scale (i.e. dp) if no MathContext object or integers are passed:
// divide: lhs, add/subtract: max(lhs, rhs), multiply: lhs + rhs

NOTES:
ICU4J
=====
IBM java package: com.ibm.icu.math.
pow's argument must be a BigDecimal.
This javascript version is used by the gwt_math project.
Among other differences, doesn't have .toPlainString() or .stripTrailingZeros().
Exports BigDecimal only.
Much faster than gwt on Firefox, on Chrome it varies with the method.
