7. If Type(lprim) is String or Type(rprim) is String, then
|
|
a. Let lstr be ? ToString(lprim).
|
|
b. Let rstr be ? ToString(rprim).
|
|
c. Return the String that is the result of concatenating lstr and rstr.

ToString Applied to the BigInt Type
|
|
|
|
1. If i is less than zero, return the String concatenation of the String "-" and ToString(-i).
|
|
2. Return the String consisting of the code units of the digits of the decimal representation of i.
