The RAND function returns numbers from the interval [0,1), and if you need to generate numbers from another interval, you should use the following formula: =RAND() * (bâa) + a. This will return random numbers from the interval [a,b) - greater than or equal to a, and less than b.
At the time, 5.4 was made available as a beta release alongside the stable 5.3.4 release. Now that 5.4 has become the latest stable Unity release, it seems the company intends to keep the program going a beta version of Unity 5.5 is slated to debut in the near future. source.
60 Co decays by beta decay to the stable isotope nickel-60 (60 Ni ). The activated nickel nucleus emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is 59 27Co + n â 60 27Co â 60 28Ni + eâ + Î½ e + gamma rays.
