Numerical Analysis Laboratory

Creating a world where calculation results can be trusted

You think PCs are a convenient machine capable of making calculations accurately and speedily, don’t you? But they are only capable of calculating speedily only if the numerals, whose number of digits is finite and which are expressed with binary numbers, are used. Even if they have a finite number of digits, errors occur in calculations, which sometimes result in grossly inaccurate answers. Our laboratory closely examines these errors to develop methods for practical use to obtain reliable results.
