Since factors adjusngjust to ostensible or ordinal estimations can't be sensibly estimated mathematically, now and again they are assembled as absolute factors, while proportion and stretch estimations are gathered as quantitative factors, which can be either discrete or consistent, because of their mathematical nature. Such differentiations can frequently be approximately related with information type in software engineering, in that dichotomous unmitigated factors might be addressed with the Boolean information type, polytomous all out factors with for arbitrary reasons doled out whole numbers in the basic information type, and constant factors with the genuine information type including drifting point calculation. In any case, the planning of software engineering information types to factual information types relies upon which classication of the last option is being executed
