#### 9.31.4 Floating Point

The floating point formats generated by directives are these.

`.float`
  `Single` precision (32-bit) floating point constants.

`.double`
  If the `-m64bit-doubles` command line option has been specified then then `double` directive generates `double` precision (64-bit) floating point constants, otherwise it generates `single` precision (32-bit) floating point constants. To force the generation of 64-bit floating point constants used the `dc.d` directive instead.
