Detailed Description

Several helper functions that returns minimal and maximal values of data types.

If you want to use Matrix_nxn and Vector_n with your own types you have to add the appropriate overloaded functions here. The maximal and minimal values should be set to values so that multiplication and division of values in the range [minValue;maxValue] can be represented by the datatype. If you don't care for under/overflows and under/overflows don't cause a crash you can set the maximal and minimal values available for the datatype.
