LINQ: How to check for zero-divider within type?

Is there a way (without using a try catch) to check for zero in ps.sum below so it doesn't throw a divide by zero error?

var procVsTotPkg = unitGroup.Join(procSums, g => new 
{
    g.DeptID,
    g.UnitLoc,
    g.Proc
},
ps => new
{                      
    DeptID = ps.key.deptID,
    UnitLoc = ps.key.unitLoc,
    Proc = ps.key.procName
}, (g, ps) => new procVSUnitTotalJoin
{
    dept = g.DeptID,
    uloc = g.UnitLoc,
    procName = g.Proc,
    unitName = g.Unit,
    unitTotal = g.CurrVal,
    procTotal = ps.sum,
    PTPcntOfUT = Math.Round((g.CurrVal / ps.sum) * 100, 2)
}).Single();
Solution 
  • PTPcntOfUT = ps.sum != 0 ? Math.Round((g.CurrVal/ps.sum)*100) : valueIfSumIsZero
