The longSum function can be used to compute the sum of two or more long values, use this instead of __intSum whenever you know your values will not be in the interval -2147483648 to 2147483647.

NameRequiredDescription
First argumentYesThe first long value.
Second argumentYesThe second long value.
nth argumentNoThe nth long value.
last argumentNoA reference name for reusing the value computed by this function. If specified, the reference name must contain at least one non-numeric character otherwise it will be treated as another long value to be added.

Examples:

Terminal window
\${__longSum(2,5,MYVAR)}

will return 7 (2+5) and store the result in MYVAR variable. So \${MYVAR} will be equal to 7.

Terminal window
\${__longSum(2,5,7)}

will return 14 (2+5+7) and store the result in MYVAR variable.

Terminal window
\${__longSum(1,2,5,\${MYVAR})}

will return 16 if MYVAR value is equal to 8, 1+2+5+${MYVAR})
