Currently, SRFI 231 requires an 8-bit floating point storage class. However:
1) There is no hardware support anywhere for such a thing. 2) There is no standard of any kind, either IEEE or otherwise, for such a thing either. 3) The sample implementation doesn't provide them. 4) I researched various articles that discuss them, and basically some are in favor of 4-bit exponent and 3-bit mantissa, and others the opposite way. Furthermore, there are different plausible values for the exponent bias: 1 is a common value, making 1/8 the minimum positive float and 15360 the maximum, but -2 is also a possibility, in which case all representable values are integral and the maximum positive float is 122880. It would be trivial to remove the reference from the SRFI and from the comments in the implementation file.
