Business Functions Library for Excel

Find Us on Facebook (opens a new tab)

Business Functions is a function library for Microsoft Excel for Windows desktop that’s been around since 2002.

We think it makes business plans, budgets, structured financings and cashflows more powerful and manageable. We found that using standard functions makes models:

  • more adaptable, because a single function call can invoke a large variety of different kinds of behaviour.
  • more accurate, because, amongst other things, over the years we’ve built in quite a sophisticated date/time system that models time periods very accurately.
  • faster to build, because you can build from an existing palette of standard algorithms, rather than reinventing the wheel every time. Its more of a building block approach.
  • quick to run, because of the fast language the functions are written in (C++).
  • probably less error prone, because of the standard and tested behaviour of the functions. Be aware, that it doesn’t eliminate the cause of

Accounting & Finance Textbooks – Open Textbook Library

Contributors: Kioko and Marlowe

Publisher: Rebus Community

Financial Strategy for Public Managers is a new generation textbook for financial management in the public sector. It offers a thorough, applied, and concise introduction to the essential financial concepts and analytical tools that today’s effective public servants need to know. It starts “at the beginning” and assumes no prior knowledge or experience in financial management. Throughout the text, Kioko and Marlowe emphasize how financial information can and should inform every aspect of public sector strategy, from routine procurement decisions to budget preparation to program design to major new policy initiatives. They draw upon dozens of real-world examples, cases, and applied problems to bring that relationship between information and strategy to life. Unlike other public financial management texts, the authors also integrate foundational principles across the government, non-profit, and “hybrid/for-benefit” sectors. Coverage includes basic principles of accounting and financial reporting, preparing and analyzing

Business and IP Centre – The British Library

To keep our users and staff safe we’ve decided to close our public spaces for the time being and suspend events. This includes the BIPC in London and our Start-ups in London Libraries workshops in borough libraries. We know that small business owners and entrepreneurs are facing an incredibly worrying and uncertain period and, at the BIPC, we want to use our online resources to offer as much support and information as we can in these difficult times.

If you were planning to attend an upcoming workshop we’ll be in touch to let you know if and when this event will be rescheduled or to arrange a refund. Please bear with us while we make these arrangements.

In the meantime some of our workshops will be running as webinars and you can watch previous events on our YouTube channel. There are also articles, blogs and Industry Guides on our website.

This library provides high-performance components leveraging the hardware
acceleration support and automatic differentiation of TensorFlow. The
library will provide TensorFlow support for foundational mathematical methods,
mid-level methods, and specific pricing models. The coverage is being
expanded over the next few months.

The library is structured along three tiers:

  1. Foundational methods.
    Core mathematical methods – optimisation, interpolation, root finders,
    linear algebra, random and quasi-random number generation, etc.

  2. Mid-level methods.
    ODE & PDE solvers, Ito process framework, Diffusion Path Generators,
    Copula samplers etc.

  3. Pricing methods and other quant finance specific utilities.
    Specific Pricing models (e.g Local Vol (LV), Stochastic Vol (SV),
    Stochastic Local Vol (SLV), Hull-White (HW)) and their calibration.
    Rate curve building, payoff descriptions and schedule generation.

We aim for the library components to be easily accessible at each level. Each

Notice: Out of an abundance of caution, all Library of Congress research centers will be closed to the public (including researchers and others with reader identification cards), from 5 p.m. on March 12 until 8:30 a.m. on April 1, 2020, to reduce the risk of transmitting COVID-19 coronavirus. All Library-sponsored public programs are also postponed or cancelled through the end of March. For more information, see:
