Abstract
PURPOSE:To convert a floating-point number into an analog value as it is without converting it into an integer by converting the mantissa part of the floating- point number into an analog value corresponding to its numeral and increasing it on the basis of an exponent function according to the numeral of the exponent part of the floating-point number. CONSTITUTION:This circuit is equipped with a digital-analog converting means 1 which converts the mantissa part M of the floating point number into the analog value corresponding to its numeral and a multiplying means 2 which increases or decreases the output analog signal Am of the digital-analog converting means 1 on the basis of the exponent function according to the numeral of the exponent part E of the floating-point number. Then the analog signal Am into which the mantissa part M is converted is outputted by the multiplying means 2 as an analog signal Ame of magnification corresponding to the numeral of the exponent part. Consequently, the floating-point number is converted into the analog value without being converted into an integer.
