gmp_init — Create GMP number
Creates a GMP number from an integer or string.
numbase2 and 62.
For bases up to 36, case is ignored;
upper-case and lower-case letters have the same value.
For bases 37 to 62,
upper-case letter represent the values 10 to
35 and lower-case letter represent the values
36 to 61.
If base is 0 then the actual
base is determined from the leading characters of num.
If the first two characters are 0x or 0X,
the string is interpreted as a hexadecimal integer.
If the first two characters are 0b or 0B,
the string is interpreted as a binary integer.
If the first two characters are 0o or 0o,
the string is interpreted as an octal integer.
Moreover, if the first character is 0 the string
is also interpreted as an octal integer.
In all other cases, the string is interpreted as a decimal integer.

It is not necessary to call this function in order to use integers or strings in place of GMP numbers in GMP functions (such as with gmp_add()). Function arguments are automatically converted to GMP numbers, if such conversion is possible and needed, using the same rules as gmp_init().
