Summary

Creates a new random number generator.

Discussion

Legacy:

arcgis.rand() is no longer supported as of ArcGIS AllSource 2.0. The arcgis.rand() function was primarily used to support creation of random values with the Calculate Value and Calculate Field tools, the Random Number Generator environment setting, and the CreateRandomValueGenerator function. Comparable functions using Python's random module should be used instead.
