Журнал змін

Версія Опис
8.0.0 scale is now nullable.
8.0.0 Dividing by 0 now throws a DivisionByZeroError exception instead of returning null.
7.2.0 num1 and num2 are no longer truncated to integer, so now the behavior of bcmod() follows fmod() rather than the % operator.
7.2.0 The scale parameter was added.
