Disclosed are a method for controlling a range of representable numbers and a device thereof. The method comprises the following steps of: receiving a floating point value represented by an exponent and a mantissa wherein each of the exponent and the mantissa is represented by a predetermined numbers of bits; determining a bit configuration of the exponent and the mantissa of the floating point value in accordance with a value of a most significant bit of the exponent of the floating point value; and determining a constant required for calculation of the floating point value in accordance with the determined bit configuration of the exponent. 지수와 가수가 각각 기 설정된 비트수로 표현되는 부동 소수점 값을 입력받고, 부동 소수점 값의 지수의 최상위 비트의 값에 따라 부동 소수점 값의 지수와 가수의 비트 구성을 결정하고, 결정된 비트 구성에 따른 지수에 따라 부동 소수점 값의 연산에 필요한 상수값을 결정하는, 표현 가능한 수의 범위를 조절하는 방법 및 장치가 개시된다.
