IntUniformDistribution
(low, high, step=1)[source]¶ A uniform distribution on integers.
This object is instantiated by
suggest_int()
, and passed tosamplers
in general.Note
If the range \([\mathsf{low}, \mathsf{high}]\) is not divisible by \(\mathsf{step}\), \(\mathsf{high}\) will be replaced with the maximum of \(k \times \mathsf{step} + \mathsf{low} < \mathsf{high}\), where \(k\) is an integer.
-
low
¶ Lower endpoint of the range of the distribution.
low
is included in the range.
-
high
¶ Upper endpoint of the range of the distribution.
high
is included in the range.
-
step
¶ A step for spacing between values.
- Raises
ValueError – If
low
value is larger thanhigh
value, orstep
value is smaller or equal to 0.
Methods
single
()Test whether the range of this distribution contains just a single value.
