Creates a GMP number from an integer or string. String representation can be decimal or hexadecimal. In the latter case, the string should start with 0x.
| Warning |
If you want to explicitely specify an integer, do not use gmp_init(12378473895798475827348979342), since first the integer-literal will be interpreted, resulting in an overflow and thus in zero, and then gmp_init is called with that zero as argument. Instead, use gmp_init('12378473895798475827348979342') |
Note: It is not necessary to call this function if you want to use integer or string in place of GMP number in GMP functions, like gmp_add(). Function arguments are automatically converted to GMP numbers, if such conversion is possible and needed, using the same rules as gmp_init().
