CAPPA Virtual Event: Rounding and Use of the Roundulator (Excel Add-in)

Wednesday, February 21, 2024

11:45 am – 1:00pm

Venue: Virtual via Webex

As production accountants, we are asked to endlessly allocate series of numbers. For example, sales volumes are allocated from a single measurement point back to multiple dimensions: producing entities, partners, products, components, purchasers, contracts, etc. It’s extremely important that when series are allocated to a new dimension all allocated results sum correctly to the control totals from the prior dimension.

This lunch & learn will explore

  • Rounding theory
  • Use of the progressive rounding algorithm
  • Rounding within Excel spreadsheets
  • Why the Excel @round function fails
  • Use of an Excel add-in file called the Roundulator_CNTL_Q that provides on-demand fixed point progressive rounding within Excel
