| Abstract: | ccording to the characteristics of various types of variables and number operations in FORTRAN language, the method that real double precision operation ed in integer operation was developed. With this method in integer operation,the result was achived that the integer significant digit is almost equal to the real double precision significant digit. |

| Keywords: | ORTRAN language double precision operation significant figure integer |
