Type BigInt

Integers are stored with the BigInt type that is composed with

• nDigs: the number of digits of the number
• Digs: the vector containing the digits

Constants

• BI__MAXDIGS = 500. The maximum number of digits for the type BigInt
• BI__IGUAL = 0
• BI__MENOR = -1
• BI__MAYOR = 1

compara(x : BigInt, y : BigInt)

Returns:

• BI_IGUAL if x == y
• BI_MENOR if x < y
• BI_MAYOR if x > y

suma(x : BigInt, y : BigInt, y : BigInt)

Returns z = x + y by reference

resta(x : BigInt, y : BigInt, y : BigInt)

Returns z = x - y by reference
