  • Constructor Details

    • SafeFraction

      public SafeFraction(org.apache.commons.lang3.math.Fraction fraction)
      Creates a new fraction instance that wraps the specified fraction with safe operations.
      Parameters:
      fraction - the fraction to wrap

    • SafeFraction

      public SafeFraction(int numerator, int denominator)
      Creates a new fraction instance that wraps the specified fraction with safe operations.
      Parameters:
      numerator - the numerator of the fraction
      denominator - the denominator of the fraction

  • Method Details

    • multiplyBy

      public org.apache.commons.lang3.math.Fraction multiplyBy(org.apache.commons.lang3.math.Fraction multiplier)
      Multiplies the value of this fraction by another, returning the result in reduced form. Since there might be an arithmetic exception due to an overflow, this method will handle this situation by calculating the multiplication based on the double values of the fractions.
      Parameters:
      multiplier - the fraction to multiply by
      Returns:
      a Fraction instance with the resulting values

    • subtract

      public org.apache.commons.lang3.math.Fraction subtract(org.apache.commons.lang3.math.Fraction subtrahend)
      Subtracts the value of another fraction from the value of this one, returning the result in reduced form. Since there might be an arithmetic exception due to an overflow, this method will handle this situation by calculating the subtraction based on the double values of the fractions.
      Parameters:
      subtrahend - the fraction to subtract
      Returns:
      a Fraction instance with the resulting values

    • subtract

      public org.apache.commons.lang3.math.Fraction subtract(int numerator, int denominator)
      Subtracts the value of another fraction from the value of this one, returning the result in reduced form. Since there might be an arithmetic exception due to an overflow, this method will handle this situation by calculating the subtraction based on the double values of the fractions.
      Parameters:
      numerator - the numerator of the fraction
      denominator - the denominator of the fraction
      Returns:
      a Fraction instance with the resulting values

    • add

      public org.apache.commons.lang3.math.Fraction add(org.apache.commons.lang3.math.Fraction summand)
      Adds the value of another fraction to the value of this one, returning the result in reduced form. Since there might be an arithmetic exception due to an overflow, this method will handle this situation by calculating the addition based on the double values of the fractions.
      Parameters:
      summand - the fraction to add
      Returns:
      a Fraction instance with the resulting values
