Numerator Command
From GeoGebra Manual
- Numerator( <Function> )
- Returns the numerator of the function.
- Example:
Numerator((3x² + 1) / (2x - 1))
yields f(x) = 3x² + 1.
- Numerator( <Number> )
- For a rational number returns its numerator. It uses a numerical method, which limits this command to numbers with small denominator. For irrational input the numerator of its continued fraction is returned.
Note: See also Denominator Command and FractionText Command.
