Description
Multiply partsPerHundred by ten for partsPerThousand.
A proportion is a ratio with a defined numerator and denominator. Fractions, percentages, and per-mille values use different scales, while a signed deviation also depends on which value is treated as the reference.
Multiply partsPerHundred by ten for partsPerThousand.

}Limitations and assumptions
- This changes the reporting scale on the same quantity basis; signed or above-100 values are accepted and physical plausibility is not checked.
- 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
Write out the numerator, denominator, and reporting scale when comparing this result with another indicator.
