在物理计算过程中,能否正确处理物理计算结果中的小数问题,是计算成功与否的关键一步.计算中,往往由于对结果的数值“入舍”处理不当,使整个计算功亏一篑.因此,掌握正确的数值处理方法,是进行物理计算必须具备的技能之一.按实际计算结果中出现的小数类型,大致有四种处理方法. In the process of physical calculation, whether or not the decimal problem in the physical calculation result can be correctly handled is a key step in the calculation of success. In the calculation, the entire calculation is often deficient due to improper handling of the numerical value of the result. Mastering the correct numerical processing method is one of the skills that must be possessed by the physical calculation. There are roughly four processing methods depending on the type of decimal that appears in the actual calculation result.
