Parameters
-
num1
-
The first summand (augent).
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init with automatic
base detection (i.e. when base is equal to 0).
-
num2
-
The second summand (addend).
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
