    <ul>

    <li>
<p>
 <tt>type&nbsp;t</tt>  <br>
the type of reals.  For <tt>MLton.LargeReal</tt> this is  <tt>LargeReal.real</tt>, for <tt>MLton.Real</tt> this is <tt>Real.real</tt>,  for <tt>MLton.Real32</tt> this is <tt>Real32.real</tt>, for  <tt>MLton.Real64</tt> this is <tt>Real64.real</tt>.

<p>
 <tt>fromWord&nbsp;w</tt> 
</p>
</li>
    <li>
<p>
 <tt>fromLargeWord&nbsp;w</tt>  <br>
convert the word <tt>w</tt> to a real value.  If the value of <tt>w</tt> is  larger than (the appropriate) <tt>REAL.maxFinite</tt>, then infinity is  returned.  If <tt>w</tt> cannot be exactly represented as a real value,  then the current rounding mode is used to determine the resulting  value. 
</p>
</li>
    <li class="gap">
<p>
 <tt>toWord&nbsp;mode&nbsp;r</tt> 
</p>
</li>
    <li>
<p>
 <tt>toLargeWord&nbsp;mode&nbsp;r</tt>  <br>
convert the argument <tt>r</tt> to a word type using the specified  rounding mode. They raise <tt>Overflow</tt> if the result is not  representable, in particular, if <tt>r</tt> is an infinity. They raise  <tt>Domain</tt> if <tt>r</tt> is NaN. 
</p>
</li>
    <li class="gap">
<p>
 <tt>MLton.Real32.castFromWord&nbsp;w</tt> 
</p>
</li>
    <li>
<p>
 <tt>MLton.Real64.castFromWord&nbsp;w</tt>  <br>
convert the argument <tt>w</tt> to a real type as a bit-wise cast. 
</p>
</li>
    <li class="gap">
<p>
 <tt>MLton.Real32.castToWord&nbsp;r</tt>

    <li>
<p>
 <tt>MLton.Real64.castToWord&nbsp;r</tt>  <br>
convert the argument <tt>r</tt> to a word type as a bit-wise cast.
