| Jan 5, 2014 at 0:18 | comment | added | B-Con | I think the canonical way to combine two numbers uniformly distributed between 0 and n is to just add them mod n. (Eg, XOR is often used for doing so, and it is just bitwise addition mod 2.) In the case of floating point, however, it may introduce precision bias due to precision limitations. | |
| Jan 4, 2014 at 23:27 | comment | added | Shad | @CodesInChaos huh, yes I could. Is that the proper way to combine two sources of entropy? [fwiw, it's javascript, so I have Math.random for free, but would need to implement sha1/another hash in code.] | |
| Jan 4, 2014 at 23:18 | comment | added | CodesInChaos | can't you just hash them and map the hash to 0..1? | |
