Functions

std::ostream & regina::operator<< (std::ostream &out, const NGroupExpressionTerm &term)
 Writes the given term to the given output stream.

Detailed Description

Various algebraic structures.

Function Documentation

std::ostream& operator<< (  std::ostream &  out,
const NGroupExpressionTerm &  term
) 
 

Writes the given term to the given output stream.

The term will be written in the format g3^-7, where in this example the term represents generator number 3 raised to the -7th power.

If the term has exponent 0 or 1, the output format will be appropriately simplified.

Parameters:
out the output stream to which to write.
term the term to write.
Returns:
a reference to the given output stream.
