PURPOSE:To realize the conversion of expression in a short time without limiting the value to be converted by converting the expression of a floating point, i.e., the internal expression of a real number of a computer into an expression based on each hardware. CONSTITUTION:The value (hexadecimal) to be converted as well as the radix and the digit number of an exponent part of the expression of said hexadecimal value are read and then the radix and the digit number of the exponent part of the converted expression are read. The specific decimal value equivalent to the unconverted value is calculated and an exponent part is calculated from said obtained value based on the radix of the expression of the conversion number. Then a mantissa part is obtained and the data on the conversion number is delivered in a hexadecimal form. In other words, the value to be converted and its data 21 are converted into a decimal expression 22. Then the conversion of expression is performed based on a converted format 23. Thus it is not required to produce a conversion program for each hardware when data are transferred between different types of hardware. |
