Modul math – odin iz naivajneyshix v Python. Etot modul predostavlyaet obshirnыy funksional dlya rabotы s chislami.

math.ceil(X) – okrugleniye do blijayshego bolshego chisla.

math.copysign(X, Y) - vozvraщayet chislo, imeyuщye modul takoy je, kak i u chisla X, a znak - kak u chisla Y.

math.fabs(X) - modul X.

math.factorial(X) - faktorial chisla X.

math.floor(X) - okrugleniye vniz.

math.fmod(X, Y) - ostatok ot deleniya X na Y.

math.frexp(X) - vozvraщayet mantissu i eksponentu chisla.

math.ldexp(X, I) - X * 2i. Funksiya, obratnaya funksii math.frexp().

math.fsum(posledovatelnost) - summa vsex chlenov posledovatelnosti. Ekvivalent vstroyennoy funksii sum(), no math.fsum() bolye tochna dlya chisel s plavayuщey tochkoy.

math.isfinite(X) - yavlyaetsya li X chislom.

math.isinf(X) - yavlyaetsya li X beskonechnostyu.

math.isnan(X) - yavlyaetsya li X NaN (Not a Number - ne chislo).
