Hello, Random Float Numbers Problem!
How Can i make Random Numbers like this

0.2
23.5
13.3
0.3
18.2
so on!

i want this for my fishing system! for fish size's!
I'll hit you up with a link when I get home. Wait a bit.

I suppose you could use something like this to generate normalized random floating point numbers (between 0 and 1):

pawn Код:
stock Float:frandnorm(const RAND_MAX = 32767)
{
//Using C's RAND_MAX constant, make a random number up to RAND_MAX and
//divide it by RAND_MAX, normalizing it (higher RAND_MAX = higher precision)
return Float:random(RAND_MAX) / Float:RAND_MAX;
}
You could then multiply that normalized value by something to produce numbers specified by a maximum value (like random()):

pawn Код:
stock Float:frand(const Float:max)
{
//Result will never exceed max, because we're multiplying a normalized (0 .. 1) value
//by the max (which will only ever give max or less)
return (frandnorm() * max);
}
Or even go as far to implement some form of range, like this:

pawn Код:
stock Float:frandrange(const Float:min, const Float:max)
{
//Just offset range of random numbers by amount
return min + frand(max-min);
}
Take for example, if I wanted to generate random numbers between 0 and 20, I might use something like:

pawn Код:
stock Float:frandnorm(const RAND_MAX = 32767)
{
return Float:random(RAND_MAX) / Float:RAND_MAX;
}

stock Float:frand(const Float:max)
{
return (frandnorm() * max);
}

main()
{
printf("0 to 20:\r\n-----");

//Generate 5 random numbers between the interval 0 to 20, and print them out!
for(new i = 0; i < 5; i++)
printf("%f", frand(20));
}
Which gives me this output:

Код:
0 to 20:
-----
18.555864
11.637317
6.126285
10.887173
1.890316
pawn Код:
new Float:MaxSize = 100.0; //This will be the largest size a fish can reach.
new Float:MinSize = 4.0; //This will be the smallest size a fish can reach.

new Float:RandSize = MinSize + float(random(floatround(MaxSize - MinSize) * 1000)) / 1000;
//Gives a random number between 4.0 (MinSize) and 100.0 (MaxSize). Results vary depending on the value of 'MaxSize' and 'MinSize'.
nvm, already done with this! btw thank u all! for help!
