Casio Scientific Calculator and Ran#
Just noticed that most of the Casio Scientific Calculator only give
3 decimal digits output from the Ran# function. When I try to do the 6 digits Random number with this input Ran# x 899999 + 10^5 Here is some of the random result with FIX 0 for 6 digits random number. 614799, 438400, 505900, 752499 and 435700 Notice that the last two digit will always have 99 and 00  To make this a rather better Random result I did this way. Ran#^Ran# x 899999 +10^5 Here is the random result 611299, 621167, 304497, 997392, 395310 and 438358 Gamo

RE: Casio Scientific Calculator and Ran#
if ran# x ran#, the result is ranged from 0.000 to 0.998001 which does not cover fully from 0 to 0.99999
How about using this : ran# x 1000 + ran# x 10^6 ? This will cover fully from 0 to 999999 12C, 15C, 15cCE, 19Bii, 22S, 35S, 39Gii, 42S, 48G, 50G, 97

Thanks HKG
That one is really good input as Ran# x 10^3 + Ran# x 10^6 Here is some of the result 464598, 764627, 949309, 651623 and 502449 Gamo

RE: Casio Scientific Calculator and Ran#
Usually on these older models, I just do Ran#+Ran#/1E3. Six digits are enough for whatever I'm doing with that old calculator. (And if not, throw in another Ran# to get 9 digits).

RE: Casio Scientific Calculator and Ran#
On a side note, unless I am mistaken random^random or random*random produce a different distribution than a uniform one.
The random*10^3 + random*^10^6 should be still a uniform distribution. Wikis are great, Contribute :)
