Description
Right-pad a fractional digit string without rounding.
Timestamp notation distinguishes written precision, quantization and carry into the next larger field. Padding a fraction, rounding it and propagating an end-of-day marker are different operations and do not establish clock accuracy.
Right-pad a fractional digit string without rounding.
When to use this tool
Use Timestamp Fraction Rightpad Without Rounding when checking one explicit timestamp precision, rounding or carry convention.
How to use the tool and how it works
- Enter digits, width. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read digits. Use the output convention below.
Right-pad a fractional digit string without rounding. Require nonempty decimal digits and whole width from current length through 64; append zeros to reach width.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| digits | Digits | Required. Text; maximum UTF-16 length 8192. |
| width | Extent on the stated coordinate or temporal basis. | Required. Safe integer; maximum 64. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| digits | Digits | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- This changes written precision, not numerical fraction or measured accuracy; truncation is rejected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use complete date-time arithmetic when a carry must change a date or interact with timezone transitions.
