nfield for Excel

Exact calculations.
A workbook you can inspect.

Bring large integers, rational arithmetic, digit cycles and musical alignment into your workbook. Keep exact values intact and choose the precision of numerical displays.

In development. The function library and documentation describe the proposed interface. A downloadable Excel add-in is not available yet.

Arbitrary precision

Work with integer and rational strings beyond ordinary cell precision. Exact arithmetic retains the value; decimal displays declare their significant digits and rounding.

=NF.BIG_ADD("9007199254740992", "1")
→ "9007199254740993"

Proposed formula and exact result. Supply the inputs as text so the spreadsheet does not round them first.

Precision and exact inputs

Explore arithmetic structure

Follow long division, compare synchronized alignment and examine finite tuning calculations. Each function describes its inputs, result and mathematical domain.
