Various algebraic structures.
REGINA_API std::ostream& regina::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.
out | the output stream to which to write. |
term | the term to write. |
