 only currently available hardware implementation of this datatype are Google's
 Cloud TPUs.  As such, this package is suitable to evaluate whether using TPUs
 would cause precision problems for any particular algorithm, even without
 access to TPU hardware.  Note that this package is designed for functionality,
 not performance, so this package should be used for precision experiments
 only, not performance experiments.")
