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>.

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.

<li>
<p>
<tt>toLargeWord mode 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.
