- Denominator( <Function> )
- Returns the denominator of a function.
- Example:
Denominator[5 / (x^2 + 2)]yields f(x)=(x2 + 2).
- Denominator( <Number> )
- For a rational number returns its denominator. It uses a numerical method, which limits this command to numbers with small denominator. For irrational input the denominator of its continued fraction is returned.
Note: See also Numerator Command and FractionText Command.
CAS Syntax
- Denominator( <Expression> )
- Returns the denominator of a rational number or expression.
- Example:
Denominator[2 / 3 + 1 / 15]yields 15.
