Description
Return expectedComplement=1-firstShare and gap=suppliedComplement-expectedComplement, requiring both supplied shares between zero and one.
A component share uses a stated whole and measurement basis. Complement shares should sum to one, while a concentration balance compares material amounts against a target composition. Fractions such as 0.25 represent 25 percent; an amount multiplied by a concentration difference is a signed material contribution.
Return expectedComplement=1-firstShare and gap=suppliedComplement-expectedComplement, requiring both supplied shares between zero and one.
When to use this tool
Use Blend Share Complement Gap when you need to check a two-share complement or one ingredient's signed contribution to a target composition.
How to use the tool and how it works
- Enter firstShare, suppliedComplement. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expectedComplement, gap. Use the output convention below.

}Limitations and assumptions
- Gap is a signed fraction difference, not a percentage numeral. The calculation does not check whether the components describe an actual two-part blend.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
For a complete blend, assemble every component on one amount and concentration basis and solve the full material balance. Check whether the physical mixing process requires density or nonadditive-volume corrections.
