DEC2BIN in WPS Spreadsheet: Create Padded Binary Labels with Honest Range Limits

• Introduced: documented by 2019-06-24 in the official WPS lesson; the first release is not established.
• Availability: Current WPS Windows documentation confirms this function. The historical lesson’s edition field is blank.
• Scope: exact current supported builds and other WPS clients remain unverified.
• Checked: October 14, 2026. Documentation and independent calculations; no native WPS execution.

=DEC2BIN(number,[places])

Although the lesson’s printed signature does not bracket places, both its definition and WPS walkthrough explicitly allow omission. Places controls output character count; it is not a rounding precision.

The source’s numeric-range bullet is literally truncated after “if number” in the captured page. Its exact accepted-number interval and corresponding range error are therefore not certified here. The ten-bit negative encoding described elsewhere in the lesson has mathematical capacity −512 through 511, but that observation is not a replacement for the missing admission rule.

The examples use small integer values and separately documented padding rules. Fractional-number coercion and current-build boundaries remain unverified.

Enter 0, 5, 37, 73 and 165 in A2:A6. In B2 use =DEC2BIN(A2) and in C2 use =DEC2BIN(A2,8), filling both down.

Only the first column is input; the other columns show expected formula output. For 37, the set weights are 32+4+1. Leading zeros align the output while preserving the same quantity.

Do arithmetic on column A rather than on a sequence of displayed binary digits. The text 100101 represents 37 in base two; interpreting those digits as an ordinary decimal quantity would use 100101 instead.

=DEC2BIN(37,6)
=DEC2BIN(37,8)
=DEC2BIN(37,10)

Expected strings are 100101, 00100101 and 0000100101. These three widths do not change 37 or establish a wider accepted-number interval.

The lesson explicitly documents truncation of noninteger places. Thus =DEC2BIN(37,8.9) has independently expected output 00100101, using width 8. This width rule must not be transferred to the separate number argument.

The current batch includes WPS-specific binary-to-octal and octal-to-decimal references. For C2:C6 from the first table, use:

=OCT2DEC(BIN2OCT(C2))

Fill down. The independently expected numeric values are 0, 5, 37, 73 and 165, recovering column A. For 37, binary 00100101 becomes octal 45, then decimal 37.

BIN2OCT and OCT2DEC each apply their own input conventions. This chain checks the chosen small examples; it does not prove that every DEC2BIN input or every possible converter boundary is supported.

The lesson says negative numbers use ten binary characters and two’s complement. Omitting places, the independently expected representations are:

The mathematical model adds 1024 to the negative value before expressing it in ten bits. For −5, that gives 1019, or 1111111011. A minus sign followed by the positive representation would be a different encoding.

The negative examples omit places as instructed by the historical wording. Invalid optional-argument precedence and the incomplete numeric admission endpoints remain unverified.

The lesson documents #NUM! when the required output has more characters than places. Since 37 needs six binary positions, =DEC2BIN(37,5) follows that documented insufficient-width condition.

It also documents #VALUE! for nonnumeric number or places, truncation of fractional places and #NUM! for negative places. Zero places and mixed-invalid-input ordering are not separately established here.

Keep the original number and the chosen representation width together. The current Windows introduction verifies this function’s identity and workflow, but does not repair the older lesson’s missing range bullet with a precise bound. Native execution was not performed, so those unresolved limits remain visible.
