r.random() → number r.random(number[, number], float=True) → number r.random(integer[, integer]) → integer
Generate a random number between given (or implied) bounds. random
takes zero, one or two arguments.
[0,1)
(from 0 up to but not including 1).[0,x)
, and will be integer unless float=True
is given as an option. Specifying a floating point number without the float
option will raise an error.[x,y)
, and will be integer unless float=True
is given as an option. If x and y are equal an error will occur, unless the floating-point option has been specified, in which case x will be returned. Specifying a floating point number without the float
option will raise an error.Note: The last argument given will always be the ‘open’ side of the range, but when generating a floating-point number, the ‘open’ side may be less than the ‘closed’ side.
Example: Generate a random number in the range [0,1)
r.random().run(conn)
Example: Generate a random integer in the range [0,100)
r.random(100).run(conn) r.random(0, 100).run(conn)
Example: Generate a random number in the range (-2.24,1.59]
r.random(1.59, -2.24, float=True).run(conn)
