type/suffixed

check for a symbol with a given suffix

 Calling Sequence type(x, suffixed(y)) type(x, suffixed(y, stype))

Parameters

 x - any expression y - symbol, string, or set or list of either symbols or strings stype - type

Description

 • A call to type suffixed with one parameter checks whether a symbol or string x has the same type as y, and x begins with the characters of y.
 • With two parameters, x is checked to see if it has the same type of and begins with the characters of y and that the balance, when parsed, is of type stype.
 • If y is a set or  list, then x is checked against each operand of y.
 • Note that x and "x" are considered to be of type suffixed(x) and suffixed("x"), respectively.  Also note that parse will automatically simplify the balance, so "x6/2" and "x4!" is an "x" suffixed by the integers 3 and 24, respectively.
