Code Select Expand

const INT32_MAX = 0x7FFFFFFF;
const INT32_MIN = 0x80000000;
FLOAT32_MAX <- INT32_MAX.tofloat();
FLOAT32_MIN <- INT32_MIN.tofloat();

srand((GetTickCount() % time()) / 3);

function RandomFloat()
{
    return (FLOAT32_MAX - FLOAT32_MIN) *
            ((rand() % 0x7FFF).tofloat() / (RAND_MAX).tofloat()) + FLOAT32_MIN;
}

function RandomFloatUpto(n)
{
    n = n.tofloat();
    return (rand() % 0x7FFF).tofloat() / (RAND_MAX / n).tofloat();
}

function RandomFloatBetween(m, n)
{
    m = m.tofloat(), n = n.tofloat();
    return (n - m) * ((rand() % 0x7FFF).tofloat() / (RAND_MAX).tofloat()) + m;
}

Example:

Code Select Expand

print( RandomFloat() );
print( RandomFloatUpto(7.4) );
print( RandomFloatBetween(3.2, 5.9) );

After a bit of number-quenching and guesswork, I finally came up with my function that takes a random number from rand() and does some maths to make the from and to function work! It supports negative numbers, too. And also a mixture of negative and positive.
Here is the code:

Code Select Expand

function Random(from, to) return (rand()*(to+1-from)) / (RAND_MAX+1)+from;Purely tested.
Hope you like it!

Quote from: Gulk on Mar 22, 2015, 11:16 AMThanks for sharing, but does anyone know how I can get a random number from a selection of numbers? Only (12,33,93)

Put them in an array and then select a random index from that array:

Code Select Expand

local rnums = [23, 56, 543, 4354, 343, 5897, 564, 425];

print(rnums[Random(0, rnums.len())]);
print(rnums[Random(0, rnums.len())]);
print(rnums[Random(0, rnums.len())]);

print(rnums[Random(0, rnums.len())]);
print(rnums[Random(0, rnums.len())]);

And string?
Edit: found, need to test
