| :: |
| |
| 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" |
