+=============================
+String Functions in LLVM-libc
+=============================
+
+-------
+Summary
+-------
+
+This site tracks the status of the implementation of string functions in LLVM
+Libc. This includes a few extra functions that are not in string.h, such as
+functions converting strings to numbers.
+
+---------------
+Source location
+---------------
+
+-   The main source for string functions is located at:
+    ``libc/src/string``.
+
+-   The source for string conversion functions is located at:
+    ``libc/src/stdlib`` and
+    ``libc/src/__support``.
+
+-   The tests are located at:
+    ``libc/test/src/string``,
+    ``libc/test/src/stdlib``, and
+    ``libc/test/src/__support``
+    respectively.
+

+
+String Conversion Functions
+============================
+
+These functions are not in strings.h, but are still primarily string
+functions, and are therefore tracked along with the rest of the string
+functions.
+
+The String to float functions were implemented using the Eisel-Lemire algorithm 
+(read more about the algorithm here: `The Eisel-Lemire ParseNumberF64 Algorithm
+<https://nigeltao.github.io/blog/2020/eisel-lemire.html>`_). This improved
+the performance of string to float and double, and allowed it to complete this
+comprehensive test 15% faster than glibc: `Parse Number FXX Test Data
+<https://github.com/nigeltao/parse-number-fxx-test-data>`_.

+---------------------------
+\<name\>_s String Functions
+---------------------------
+
+Many String functions have an equivalent _s version, which is intended to be
+more secure and safe than the previous standard. These functions add runtime
+error detection and overflow protection. While they can be seen as an
+improvement, adoption remains relatively low among users. In addition, they are
+being considered for removal, see 
+`Field Experience With Annex K — Bounds Checking Interfaces
+<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1967.htm>`_. For these reasons, 
+there is no ongoing work to implement them.
