2019-12-06T07:29:41Z (GMT) by Oyanarte Portilho
Abstract A package written in Fortran is presented that allows multiple precision calculations through simple subroutine calls. The package can be used in an already existing program or in a new program after proper substitution of Fortran statements by the above mentioned calls. The available subroutines range from basic arithmetic operations to trigonometric functions and provide up to 300 digit precision or higher on VAX machines. Title of program: MP Catalogue Id: ABRJ_v1_0 Nature of problem In many situations a higher precision than the one furnished by the machine is necessary to get confinding results, like in variational calculations in Nuclear Physics, when large harmonic oscillator bases are used. Versions of this program held in the CPC repository in Mendeley Data ABRJ_v1_0; MP; 10.1016/0010-4655(90)90183-2 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
