Decimal amount not displaying in log Analytics query

[Deleted]

Hi I have a really simple query

ApplicationInsights

| where TelemetryType == "Availability"

|summarize count() by AvailabilityResult

|summarize failedCount=sumif(count_, AvailabilityResult == "Fail"), totalCount=sum(count_)

|extend (failedCount / totalCount)

but the "extend (failedCount / totalCount)" is just displaying as a 0, its a really small decimal .003...how do I display this as a decimal value?

Two valid options:

1) explicit type casting to floating point:

... | extend failureRate = todouble(failedCount) / todouble(totalCount)

2) implicit type casting:

... | extend failureRate = failedCount * 1.0 / totalCount

[#3]

|summarize count() by AvailabilityResult

|summarize failedCount=sumif(count_, AvailabilityResult == "Fail")+0.00000, totalCount=sum(count_)+0.00000

|extend avail=100 - ((failedCount / totalCount)*100)

adding by this decimal forces a cast to decimal.
