Your expectation is wrong.
All the above functions do what they are expected to do.
We can not expect that random number generators generate "every" number in a series. Also they may generate duplicates.
It is for us (the programmer) to use the random function to get what we want.
For example, if we want a function to generate every number between 1 to 999 without repeating then we can try this approach.
- Code: Select all Expand view
function RandomList
local aList := Array( 999 )
local nAt, aRandom := {}
AEval( aList, { |u,i| aList[ i ] := i } )
do while Len( aList ) > 0
nAt := HB_RandomInt( 1, Len( aList ) )
AAdd( aRandom, aList[ nAt ] )
ADel( aList, nAt, .t. )
enddo
XBROWSER aRandom SHOW RECID
return nil
This function gives a list of randomly generated list of numbers from 1 to 999 without repeating and covering all numbers.
