Usage notes:

• Certain formulation can cause unexpected behaviour. As examples: division by zero division by negative number, example: 48/-7 using text or char except for callback for operand using another operator (<, >, =,etc)

• Supported operators: +, -, *, /
• Arguments can't start and end with operator (+, -, *, / )
• Two operators one after the other will cause an error
• The priority for operator is still working, which mean that the multiplication and division will be executed first followed by addition and substraction
  • Parentheses ((, )) can't be used to change operator priority.
• Integer division method will be used for division.
• Callback don't work with float numbers

Here are some common operations:

Example code:

<SnomIPPhoneText>
    <Text>
	4=$(math_eval:4)<br />
	1+2=$(math_eval:1+2)<br />
	1-2=$(math_eval:1-2)<br />
	max_registrations-1=$(math_eval:$(max_registrations)-1)<br />
	2*3=$(math_eval:2*3)<br />
	0*4=$(math_eval:0*4)<br />
	4/2=$(math_eval:4/2)<br />
	10/3=$(math_eval:10/3)<br />
	47/7=$(math_eval:47/7)<br />
	0/4=$(math_eval:0/4)<br />
	1+3*4=$(math_eval:1+3*4)<br />
	1-10/5=$(math_eval:1-10/5)<br />
	109/10/4=$(math_eval:109/10/4)<br />
    </Text>
</SnomIPPhoneText>
