gmp_init Create GMP number &reftitle.description; resourcegmp_init mixednumber intbase0 Creates a GMP number from an integer or string. &reftitle.parameters; number An integer or a string. The string representation can be decimal, hexadecimal or octal. base The base. The base may vary from 2 to 36. If base is 0 (default value), the actual base is determined from the leading characters: if the first two characters are 0x or 0X, hexadecimal is assumed, otherwise if the first character is "0", octal is assumed, otherwise decimal is assumed. &reftitle.returnvalues; &gmp.return; &reftitle.changelog; &Version; &Description; 4.1.0 The optional base parameter was added. &reftitle.examples; ]]> &reftitle.notes; 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.
