+------
+
+.. code::
+
+   #include <prdtoa.h>
+
+   void PR_cnvtf (
+     char *buf,
+     PRIntn bufsz,
+     PRIntn prcsn,
+     PRFloat64 fval);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+``buf``
+   The address of the buffer in which to store the result.
+``bufsz``
+   The size of the buffer provided to hold the result.
+``prcsn``
+   The number of digits of precision to which to generate the floating
+   point value.
+``fval``
+   The double-precision floating point number to be converted.

+Description
+-----------
+
+:ref:`PR_cnvtf` is a simpler interface to convert a floating point number
