Jon Turney 81a7c8c37f doc: Fix some inconsistent QUICKREF lines makedoc defines a command as 'all upper case, and alone on a line'. A few QUICKREF lines currently violate this by having some additional text after the QUICKREF. So, currently, these lines are treated as an unknown command. This is benign as QUICKREF currently does nothing but produce some ignored output on stderr. I'm not sure what the intent of QUICKREF is. 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * libm/mathfp/s_acos.c: Fix QUICKREF. * libm/mathfp/e_acosh.c: Ditto. * libm/math/w_asin.c: Ditto. * libm/mathfp/e_acosh.c: Ditto. * libm/mathfp/s_acos.c: Ditto.

README

This directory was an experiment to use floating-point operations to implement
the math library when a processor had a floating-point instruction set.  The
experiment was a failure in that some of the algorithms chosen (e.g. recursive
algorithms for sin/cos, etc..) are too simple and do not provide proper accuracy 
nor handle very large or very small inputs adequately.

The code is considered moth-balled.  The stable math library routines can be
found in libm/math and the configuration option to use this has been removed.

If you wish to experiment with the concept, please feel free and report back if
you have major improvements.
