Description
Return binCount/totalCount, bin width, and fraction divided by width.
Blood-cell research counts require a defined eligible population, exclusion rule, sampled volume, and dilution basis. Their arithmetic fractions and densities are separate from validated laboratory results and clinical reference intervals.
Return binCount/totalCount, bin width, and fraction divided by width.
When to use this tool
Use Hematology Histogram One Bin Width Term when you need one transparent research count or denominator component.
How to use the tool and how it works
- Enter binCount, totalCount, lower, upper. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read probabilityMass, density, width. Use the output convention below.
Require positive totalCount, binCount within it, and upper greater than lower. Return binCount/totalCount, bin width, and fraction divided by width.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| binCount | Bin Count | Required. Safe integer; minimum 0. |
| totalCount | Total Count | Required. Safe integer; minimum 1. |
| lower | Lower | Required. Finite number. |
| upper | Upper | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| probabilityMass | Probability Mass | Required. Finite number. |
| density | Density | Required. Finite number. |
| width | Interval or dimension span under the stated unit and endpoint convention. | Required. Finite number. |

}Limitations and assumptions
- Density is probability per bin-coordinate unit rather than probability mass or cell concentration; no full histogram, analyzer calibration, or clinical interpretation is evaluated.
- 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
Review the complete laboratory protocol, quality controls, uncertainty, and appropriate professional interpretation.
