An example of a floating point arithmetic method comprises: storing bit information of a mantissa of at least one operand selected from among at least two operands based on a result of comparing exponents of the at least two operands being input; outputting an operation result of higher bits by calculating the at least two operands; and outputting an operation result of lower bits by adding, to the bit information of the mantissa of the at least one operand, a bit lost through a normalization operation and a rounding operation in the calculation of the at least two operands. Accordingly, the method can accelerate high-precision arithmetic by adding, to a floating point operator, hardware that calculates an error in a floating point addition operation, and, via instructions supporting the same, can configure an efficient processor.
