 .SH DESCRIPTION
-The
-.BR cbrt ()
-function returns the (real) cube root of \fIx\fP.
+These functions return the (real) cube root of
+.IR x .
 This function cannot fail; every representable real value has a
 representable real cube root.
 .SH RETURN VALUE
 These functions return the cube root of
 .IR x .
-
+.PP
 If
 .I x
-is +0, -0, positive infinity, negative infinity, or NaN,
+is +0, \-0, positive infinity, negative infinity, or NaN,
 .I x
 is returned.
