Abstract:
A method for operating a digital computer having computer readable memory means is used to determine whether a given value is included in an ordered table of values stored in the memory means. The method commences by defining lower and upper boundary positions and lower and upper boundary values. The lower and upper boundary positions are defined to be the first and last table positions, respectively, and the lower and upper boundary values are defined to be the values in the lower and upper boundary positions, respectively. An assumed position is then determined for the given value between the lower and upper boundary positions, and a test value is set equal to the value at the assumed position. The test value is then compared to the given value. If the test and given values are equal, then the given value is in the table at the assumed position.
