4.11 number

Numbers are elements from the coefficient field (or ground field). They can only be defined or accessed with respect to a basering which determines the coefficient field. See ring declarations for declarations of coefficient fields.

Warning: Beware of the special meaning of the letter e (immediately following a sequence of digits) if the field is real (or complex). See number operations, Miscellaneous oddities.
