<p>Note that the following macros perform multiple evaluations of their
arguments, so they should not be used with arguments that have side
effects (such as a call to a random number generator).

<dl>
<dt><a name="index-GSL_005fMAX"></a>Macro: <strong>GSL_MAX</strong> <em>(a, b)</em></dt>
<dd><a name="index-maximum-of-two-numbers"></a>
<p>This macro returns the maximum of <var>a</var> and <var>b</var>. It is defined
as <code>((a) > (b) ? (a):(b))</code>.
</p></dd></dl>
<dl>
<dt><a name="index-GSL_005fMIN"></a>Macro: <strong>GSL_MIN</strong> <em>(a, b)</em></dt>
<dd><a name="index-minimum-of-two-numbers"></a>
<p>This macro returns the minimum of <var>a</var> and <var>b</var>. It is defined as
<code>((a) < (b) ? (a):(b))</code>.
</p></dd></dl>
<dl>
<dt><a name="index-GSL_005fMAX_005fDBL"></a>Function: <em>extern inline double</em> <strong>GSL_MAX_DBL</strong> <em>(double <var>a</var>, double <var>b</var>)</em></dt>
<dd><p>This function returns the maximum of the double precision numbers
<var>a</var> and <var>b</var> using an inline function. The use of a function
allows for type checking of the arguments as an extra safety feature. On
platforms where inline functions are not available the macro
<code>GSL_MAX</code> will be automatically substituted.
</p></dd></dl>
<dl>
<dt><a name="index-GSL_005fMIN_005fDBL"></a>Function: <em>extern inline double</em> <strong>GSL_MIN_DBL</strong> <em>(double <var>a</var>, double <var>b</var>)</em></dt>
<dd><p>This function returns the minimum of the double precision numbers
<var>a</var> and <var>b</var> using an inline function. The use of a function
allows for type checking of the arguments as an extra safety feature. On
platforms where inline functions are not available the macro
<code>GSL_MIN</code> will be automatically substituted.

<dd><p>These functions return the maximum or minimum of the integers <var>a</var>
and <var>b</var> using an inline function. On platforms where inline
functions are not available the macros <code>GSL_MAX</code> or <code>GSL_MIN</code>
will be automatically substituted.
</p></dd></dl>

<dd><p>These functions return the maximum or minimum of the long doubles <var>a</var>
and <var>b</var> using an inline function. On platforms where inline
functions are not available the macros <code>GSL_MAX</code> or <code>GSL_MIN</code>
will be automatically substituted.
