In: Computer Programming, C Programming, JavaScript [Edit categories]

Answer:

not 100% sure if this is what you are asking for but here it goes.

you have a number 11110000 (binary) and you want 00001111 (binary)?

you want to use the xor operator ^

value = 0xf0; //11110000 binary
printf("before %d\n");
value ^= 0xff; //11111111 binary
printf("after%d\n");

output:
before 240
after 15

240 in binary is 11110000
15 in binary is 00001111
