Title of program: MISHA computer may be insufficient. The present subroutine package makes it possible to perform calculations with any arithmetic Catalogue number: AAXU precision, i.e. on any number of decimal digits. Both integer and floating-point arithmetic are included. Program obtainable from: CPC Program Library, Queen's Urnversity of Belfast, N. Ireland (see application form in this issue) Method of solution The calculations are based on the central numeric system. Computer. HP 1000 and EC 1040; Installation: Nuclear Physics Every variable (integer as well as floating-point) is stored in an Institute and Nuclear Research Institute, respectively, kel near integer array of proper length, each element of which contains Prague, Czechoslovakia one cental digit. The subroutines performing the particular arithmetic operations are coded according to the ordinary Operating system: RTE 4b and os/21.8F formulae for addition, multiplication, etc., and they utilize the hardware integer arithmetic. Programming language used: FORTRAN IV High speed storage required: depends on the selected precision;
Restriction on complexity of the problem for 60 decimal digits it requires 16 kwords on HP and 40
The restriction on the precision is determined only by the kwords on EC computer storage and by the computer time.
No. of bits in a word: 16 Typical running time
The running time depends on the precision required. More Peripherals used: line pnnter and in some cases an auxiliary detailed information is given m section 7. The test run took magnetic device (disc or tape) -see long wnte-up about 17 mm on both EC 1040 and HP 1000 computers.
No. of lines in combined program and test deck: 2456 Unusual features of the program Keywords: high precision calculation
In the present version, the arrays used as "variables" are composed of 16-bit integers. To employ a computer with Nature of physical problem longer integers, the cards "INTEGER * 2 should be re-In certain applications the standard hardware precision of a moved from all the subroutines of the package.
