longadd()

Description

This function is used to add 64-bit numbers.

Mathematical function which adds val with val2 (val+val2=res).

Syntax

longadd(valL, valH, val2L, val2H, resL, resH);

Parameters

Variable	Input

Variable	Input
`valL`	variable which holds least significant 32 bits of number you want to add with val2.
`valH`	variable which holds most significant 32 bits of number you want to add with val2.
`val2L`	variable which holds least significant 32 bits of number you want to add with val.
`val2H`	variable which holds most significant 32 bits of number you want to add with val.
`rezL`	variable which will hold most significant 32 bits of addition result between val and val2.
`rezH`	variable which will hold least significant 32 bits of addition result between val and val2.

Returns

Always returns SCRIPT_OPERATION_SUCCESS.

Function call example

Example of 64 bit addition

new Number1MSB = 3450;
new Number1LSB = 5310;
new Number2MSB = 6549;
new Number2LSB = 3578;
new ResultMSB  = 0;
new ResultLSB  = 0;

main()
{
	longadd(Number1LSB, Number1MSB, Number2LSB, Number2MSB, ResultLSB, ResultMSB); // ResultMSB = 9999 and ResultLSB = 8888

    for(;;)
	{
		Delay(1000);
	}
