+# NAME
+
+u64.h - 64bit unsigned integers
+
+# SYNOPSIS
+
+    #include <limb/u64.h>

+slightly different interfaces.
+
+## Constants
+
+The following constants are defined :
+
+: *U64_FMT*
+:: Maximum length for a byte array that can hold an u64 value in decimal
+:: representation, plus a NUL-terminating byte
+
+: *U64_FMTG*
+:: Same as *U64_FMT* but with thousand-separators
+
+: *U64_BFMT*
+:: Same as *U64_FMT* but for binary
+
+: *U64_OFMT*
+:: Same as *U64_FMT* but for octal
+
+: *U64_XFMT*
