<p>The assembler recognizes both the <small>IEEE</small> floating-point instruction and
|
|
the hexadecimal floating-point instructions. The floating-point constructors
|
|
‘<samp>.float</samp>’, ‘<samp>.single</samp>’, and ‘<samp>.double</samp>’ always emit the
|
|
<small>IEEE</small> format. To assemble hexadecimal floating-point constants the
|
|
‘<samp>.long</samp>’ and ‘<samp>.quad</samp>’ directives must be used.
