    • isWithinTolerance

      boolean isWithinTolerance(float value1, float value2)
      Indicates whether the specified values are equal under the tolerance.
      Parameters:
      value1 - the first value to compare
      value2 - the second value to compare
      Returns:
      true if the two values lie with the error bounds, otherwise false

    • isWithinTolerance

      boolean isWithinTolerance(double value1, double value2)
      Indicates whether the specified values are equal under the tolerance.
      Parameters:
      value1 - the first value to compare
      value2 - the second value to compare
      Returns:
      true if the two values lie with the error bounds, otherwise false

    • isWithinTolerance

      boolean isWithinTolerance(BigDecimal value1, BigDecimal value2)
      Indicates whether the specified values are equal under the tolerance.
      Parameters:
      value1 - the first value to compare
      value2 - the second value to compare
      Returns:
      true if the two values lie with the error bounds, otherwise false
