problem

[hitendrapharmacy]

please resolve ./modmath result to HEX and DEC

[albertobsd]

for mothmath add the next line:

gmp_printf("Result: %Zd\n\n",C);

just before of the line 87

gmp_printf("Result: %Zx\n\n",C);

the code will look like:

gmp_printf("Result: %Zx\n\n",C);  //Hexadecimal '%Zx'
gmp_printf("Result: %Zd\n\n",C); //Decimal '%Zd'

Edit the code, I don't know why you want the result in Decimal, no one software accepts keys in Decimal, all use Hexadecimal or WIF format
