 ::
 
-  math(EXPR <output-variable> <math-expression>)
+  math(EXPR <output-variable> <math-expression> [OUTPUT_FORMAT <format>])
 
 ``EXPR`` evaluates mathematical expression and returns result in the
 output variable.  Example mathematical expression is ``5 * (10 + 13)``.
 Supported operators are ``+``, ``-``, ``*``, ``/``, ``%``, ``|``, ``&``,
 ``^``, ``~``, ``<<``, ``>>``, and ``(...)``.  They have the same meaning
 as they do in C code.
+
+Numeric constants are evaluated in decimal or hexadecimal representation.
+
+The result is formatted according to the option "OUTPUT_FORMAT" ,
+where ``<format>`` is one of:
+::
+
+ HEXADECIMAL = Result in output variable will be formatted in C code
+ Hexadecimal notation.
+ DECIMAL = Result in output variable will be formatted in decimal notation.
+
+
+For example::
+
+  math(EXPR value "100 * 0xA" DECIMAL)  results in value is set to "1000"
+  math(EXPR value "100 * 0xA" HEXADECIMAL)  results in value is set to "0x3e8"
