POPIS
       These functions compute the remainder of dividing x by y.  The return
       value is x-n*y, where n is the value x / y, rounded to the nearest
       integer.  If the absolute value of x-n*y is 0.5, n is chosen to be
       even.

       Tyto funkce nejsou ovlivneny aktualnim zaokrouhlovacim modem (viz
       fenv(3)).

       Funkce drem() dela presne to same.

NAVRATOVE HODNOTY
       V pripade uspechu tato funkce vraci zbytek po deleni v plovouci radove
       carce x-n*y. Pokud je navratova hodnota 0 ma znamenko shodne s x.

       Je-li x nebo y NaN, je vraceno NaN.

       Pokud je x nekonecno a y neni NaN je vystavena domenova chyba a je
       vraceno NaN.

       Pokud je y nula a x neni NaN je vystavena domenova chyba a je vraceno
       NaN.

CHYBOVE STAVY
       Pro vice informaci zda funkce pri svem volani generovala chybu viz
       math_error(7).

       Mohou se objevit nasledujici chyby:

       Domenova chyba: x je nekonecno a y neni NaN
              errno je nastaveno na EDOM (viz CHYBY). Je signalizovana vyjimka
              plovouci carky (FE_INVALID).

              These functions do not set errno for this case.

       Domenova chyba: y je nula
              errno je nastaveno na EDOM. Je signalizovana vyjimka plovouci
              carky (FE_INVALID).

CHYBY
       Before glibc 2.15, the call

           remainder(nan(""), 0);

       returned a NaN, as expected, but wrongly caused a domain error.  Since
       glibc 2.15, a silent NaN (i.e., no domain error) is returned.

       Before glibc 2.15, errno was not set to EDOM for the domain error that
       occurs when x is an infinity and y is not a NaN.
