Hi to everybody
I am doing some experiments about random numbers.
I need "extreme speed" for the generation for numbers from 1 to 8.
Generating 500_000_000 numbers with this code:
-----------------------------
import std.stdio, std.array, std.random;
void main()
{
byte c;
writeln("Start");
for(int k=1;k<=500_000_000;k++)
c=uniform!ubyte() % 8 +1; //<<< ======= RANDOM
writeln("Stop");
}
-----------------------------
I get these results:
c=uniform!ubyte() % 8 +1; ======>>> Execution time: 15.563 s
c=cast(byte)uniform(1, 9); ======>>> Execution time: 24.218 s
Do you know other faster functions or methods to generate random
numbers?
For me the "goodness of random" is NOT important.
Thank you very much
