- Denominator[ <Expression> ]
- Returns the denominator of a rational number or expression.
- Example:
Denominator[2 / 3 + 1 / 15]yields 15.
Note:
See also Numerator Command.
Note:
For a fast numerical method (so long as the numbers aren't too big) you can use these in the Input Bar: CommonDenominator[a,a] for denominator and round(a*CommonDenominator[a,a]) for Numerator
