+</h4>

+<div>
+
+<h5>Syntax:</h5>
+<p>This is an overloaded intrinsic. You can use <tt>llvm.floor</tt> on any
+   floating point or vector of floating point type. Not all targets support all
+   types however.</p>
+
+<pre>
+  declare float     @llvm.floor.f32(float  %Val)
+  declare double    @llvm.floor.f64(double %Val)
+  declare x86_fp80  @llvm.floor.f80(x86_fp80  %Val)
+  declare fp128     @llvm.floor.f128(fp128 %Val)
+  declare ppc_fp128 @llvm.floor.ppcf128(ppc_fp128  %Val)
+</pre>
+
+<h5>Overview:</h5>
+<p>The '<tt>llvm.floor.*</tt>' intrinsics return the floor of
+   the operand.</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>floor</tt> functions
+   would, and handles error conditions in the same way.</p>
