Detailed Description
template<int k>
class Dune::bigunsignedint< k >
class Dune::bigunsignedint< k >
Portable very large unsigned integers.
Implements (arbitrarily) large unsigned integers to be used as global ids in some grid managers. Size is a template parameter.
- Template Parameters
-
k Number of bits of the integer type
Member Function Documentation
◆ operator%()
template<int k>
bigunsignedint< k > Dune::bigunsignedint< k >::operator% | ( | const bigunsignedint< k > & | x | ) | const |
modulo
- Warning
- This function is very slow and its usage should be prevented if possible
◆ operator/()
template<int k>
bigunsignedint< k > Dune::bigunsignedint< k >::operator/ | ( | const bigunsignedint< k > & | x | ) | const |
divide
- Warning
- This function is very slow and its usage should be prevented if possible
