      The Boost Numeric Conversion library is a collection of tools to describe and

      values for the <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.range_and_precision" title="Range and Precision">range</a>
      of a numeric type.
    </p>

129	The Boost Numeric Conversion library is a collection of tools to describe and
130	perform conversions between values of different <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.numeric_types" title="Numeric Types">numeric
131	types</a>.

133	<p>
134	The library includes a special alternative for a subset of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">numeric_limits</span><span class="special"><></span></code>, the <a class="link" href="boost_numericconversion/bounds___traits_class.html" title="bounds<> traits class">bounds<></a>
135	traits class, which provides a consistent way to obtain the <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.range_and_precision" title="Range and Precision">boundary</a>
136	values for the <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.range_and_precision" title="Range and Precision">range</a>
137	of a numeric type.
138	</p>

140	It also includes a set of <a class="link" href="boost_numericconversion/conversion_traits___traits_class.html" title="conversion_traits<> traits class">trait
141	classes</a> which describes the compile-time properties of a conversion
142	from a source to a target numeric type. Both <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.c___arithmetic_types" title="C++ Arithmetic Types">arithmetic</a>
143	and <a class="link" href="boost_numericconversion/definitions.html#boost_numericconversion.definitions.numeric_types" title="Numeric Types">user-defined
