* @dev computes e ^ (x / FIXED_1) * FIXED_1

* auto-generated via 'PrintFunctionOptimalExp.py'
* Detailed description:
* - Rewrite the input as a sum of binary exponents and a single residual r, as small as possible
* - The exponentiation of each binary exponent is given (pre-calculated)
* - The exponentiation of r is calculated via Taylor series for e^x, where x = r
* - The exponentiation of the input is calculated by multiplying the intermediate results above
* - For example: e^5.521692859 = e^(4 + 1 + 0.5 + 0.021692859) = e^4 * e^1 * e^0.5 * e^0.021692859

*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

When it is started, they instantly seek contact with one another, troop together, fur to fur.
We are awoooooooing to gather people with the same spirit as us like a wolf - sharp intelligence, appetite for freedom, strong instincts and always ready to hunt.

Green Wall Street
Everything is a joke until its not….
Back in 2017, Warren Buffet said “"People get excited from big price movements, and Wall
Street accommodates... Stay away from bitcoin. It's a mirage, basically. The idea that it has
some huge intrinsic value is just a joke, in my view -- you can't value bitcoin because it's not a
value-producing asset."”
Wall Street has been the historic headquarters of some of the largest centralized global
brokerages and investment banks. Wall Street symbolizes the economic inequality and the
influence of money in politics which take advantage of asymmetric information of so called
financial professionals and the public.
Green Wall Street is dedicated to mark the era when Satoshi firstly established the idea of
bitcoin and decentralised economy. This was designed as the defense line to protect the
transaction of digital currency from the problem of double spending and a bunch of
inefficiencies which the fiat economy was unable to solve. A digital currency or token used to be
duplicated in multiple transactions and the construction of the Green Wall Street has
successfully enabled Satoshi to mitigate this traditional problem and fully challenge the
traditional financial system..
The token of Green Wall Street is designed to pay tribute to those who sacrifice and strong
followers who dedicate their life to fight the war against the disgusting Wall Street blood
suckers. Show your support and become part of the supporting community.

* TIP: For a detailed writeup see our guide

* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
