Simple function to convert hexadecimal figures to decimal. It need to define a constant table hex
Shell
| BEGIN { |
| for (i = 0; i < 10; i++) hex[i] = i |
| hex["a"] = hex["A"] = 10 |
| hex["b"] = hex["B"] = 11 |
| hex["c"] = hex["C"] = 12 |
| hex["D"] = hex["d"] = 13 |
| hex["e"] = hex["E"] = 14 |
| hex["f"] = hex["F"] = 15 |

| function hex2dec(h, i, x) { |
| x = 0 |
| for (i = 1; i <= length(h); i++) |
| x = x * 16 + hex[substr(h, i, 1)] |
| return x |
