87 file defines four types:  `float32' (single precision), `float64' (double
88 precision), `floatx80' (extended double precision), and `float128'
89 (quadruple precision).  The `float32' and `float64' types are defined in
147 For extended double precision (`floatx80') only, the rounding precision
154 operations are rounded (as usual) to the full precision of the extended
155 double-precision format.  Setting `floatx80_rounding_precision' to 32
156 or to 64 causes the operations listed to be rounded to reduced precision
157 equivalent to single precision (`float32') or to double precision
158 (`float64'), respectively.  When rounding to reduced precision, additional
221 integers to double precision and larger formats are also exact, and likewise
