#109473 - Why not use a table? Responding to: ???'s previous message |
If there is only 16 bits to play with, why not use a table of masks? const uint16 bit_mask[16]={0x0001,0x0003,0x0007......... value |= bit_mask[i]; Job done! |

| why not just |= bits_to_be_added | 01/01/70 00:00 | |

| ah | 01/01/70 00:00 | |
| bang on | 01/01/70 00:00 | |
| Try an Array | 01/01/70 00:00 | |
| |= 2^RightMostBits -1; // sure? | 01/01/70 00:00 | |
| You are correct about ^ != pow() | 01/01/70 00:00 | |
