{ "_id": "6a2be6e23efcd9bda42cd879", "Package": "float", "Type": "Package", "Title": "32-Bit Floats", "Version": "0.3-3", "Description": "R comes with a suite of utilities for linear algebra with\n\"numeric\" (double precision) vectors/matrices. However,\nsometimes single precision (or less!) is more than enough for a\nparticular task. This package extends R's linear algebra\nfacilities to include 32-bit float (single precision) data.\nFloat vectors/matrices have half the precision of their\n\"numeric\"-type counterparts but are generally faster to\nnumerically operate on, for a performance vs accuracy\ntrade-off. The internal representation is an S4 class, which\nallows us to keep the syntax identical to that of base R's.\nInteraction between floats and base types for binary operators\nis generally possible; in these cases, type promotion always\ndefaults to the higher precision. The package ships with\ncopies of the single precision 'BLAS' and 'LAPACK', which are\nautomatically built in the event they are not available on the\nsystem.", "License": "BSD 2-clause License + file
