- 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 a 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.
