C - zaokrouhlovani

[Miroslav Šinko]

Delenie celych cisel v C sa nezaokruhluje. Norma to definuje takto:

The result of the / operator is the quotient from the division of the
first operand by the
second; the result of the % operator is the remainder. In both
operations, if the value of
the second operand is zero, the behavior is undefined.
