[Gambas-user] Rnd Wiki

[Demosthenes Koptsis]

I wrote something that i think describes better the Rnd().

If you like it you can use or modify it for the wiki.

------------------------------------------------------------------------
Float = Rnd ( [ Min [ , Max ] )

Compute a pseudo-random floating point number between a lower Min limit
value and an upper Max limit value. 

# If no parameters is specified the default value for lower limit, Min, 
  is 0 and for upper limit, Max, is 1. 
  The function returns a pseudo-random number in the interval [ 0 , 1 ].

# If only one parameter is specified this parameter is used as the 
  upper limit, so argument1, Min will be used as upper limit. The  
  lower limit is by default 0. 
  The function returns a pseudo-random in the interval [ 0 , Min ].

# If both parameters are specified, Min is the lower limit and Max the
  upper limit.
  The function returns a pseudo-random in the interval [ Min , Max ]. 

Note that the higher born of the interval is never returned.
