<h4>
<a name="int_exp">'<tt>llvm.exp.*</tt>' Intrinsic</a>
</h4>
<div>
<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.exp</tt> on any
floating point or vector of floating point type. Not all targets support all
types however.</p>
<pre>
declare float @llvm.exp.f32(float %Val)
declare double @llvm.exp.f64(double %Val)
declare x86_fp80 @llvm.exp.f80(x86_fp80 %Val)
declare fp128 @llvm.exp.f128(fp128 %Val)
declare ppc_fp128 @llvm.exp.ppcf128(ppc_fp128 %Val)
</pre>
<h5>Overview:</h5>
<p>The '<tt>llvm.exp.*</tt>' intrinsics perform the exp function.</p>
<h5>Arguments:</h5>
<p>The argument and return value are floating point numbers of the same
type.</p>
<h5>Semantics:</h5>
<p>This function returns the same values as the libm <tt>exp</tt> functions
would, and handles error conditions in the same way.</p>
</div>

<h4>
<a name="int_log">'<tt>llvm.log.*</tt>' Intrinsic</a>
</h4>
<div>
<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.log</tt> on any
floating point or vector of floating point type. Not all targets support all
types however.</p>
<pre>
declare float @llvm.log.f32(float %Val)
declare double @llvm.log.f64(double %Val)
declare x86_fp80 @llvm.log.f80(x86_fp80 %Val)
declare fp128 @llvm.log.f128(fp128 %Val)
declare ppc_fp128 @llvm.log.ppcf128(ppc_fp128 %Val)
</pre>
<h5>Overview:</h5>
<p>The '<tt>llvm.log.*</tt>' intrinsics perform the log function.</p>
<h5>Arguments:</h5>
<p>The argument and return value are floating point numbers of the same
type.</p>
<h5>Semantics:</h5>
<p>This function returns the same values as the libm <tt>log</tt> functions
would, and handles error conditions in the same way.</p>
