A MODE argument must be the printable name of a machine mode,
without quotation marks or trailing "mode". For instance, SI.
- A BITSIZE, BYTESIZE, or COUNT argument must be a positive integer
+ A PRECISION, BYTESIZE, or COUNT argument must be a positive integer
constant.
A FORMAT argument must be one of the real_mode_format structures

All of the bits of its representation are significant.

FLOAT_MODE (MODE, BYTESIZE, FORMAT);
declares MODE to be of class FLOAT and BYTESIZE bytes wide,

RESET_FLOAT_FORMAT (MODE, FORMAT);
declares a mode of class PARTIAL_INT with the same size as
MODE (which must be an INT mode). The name of the new mode
is made by prefixing a P to the name MODE. This statement
