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