public interface IntegerConvertor
Defines fields which can convert numbers to or from integers. This is needed for the power operator as integer powers are considerably easier to calculate. It can also be used to get the size of a matrix or specify matrices of a specific size.

Since Jep 4.1 extensions 2.2 this has been moved to the com.singularsys.extensions.field.implementations package from the the com.singularsys.extensions.field package.
