- Numerator[ <Function> ]
- Returns the numerator of the function.
- Example:
Numerator[(3x² + 1) / (2x - 1)]yields f(x) = 3x² + 1.
CAS Syntax
- Numerator[ <Expression> ]
- Returns the numerator of a rational number or expression.
- Example:
Numerator[2/3 + 1/15]yields 11.
Note:
See also Denominator 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
