how to convert number to string using tostring function?

[LearningGuy]

Hello,
how to convert number to string using tostring function?
I tried using tostring function, but the result is still number
See below.   Thank you!!

| makeresults

| eval num = 1
| eval var_type = typeof('num')

| eval num2 = tostring(num)
| eval var_type2 = typeof('num2')

[LearningGuy]

They both became String.     Num should be number.  Thanks

Hi @LearningGuy,

the second it's a string, you transformed it using the tostring function, infact you have the commas.

Ciao.

@gcusello 
Yes but why the first one is also string?
The first one is number.
Should I remove " " from typeof?        Thanks

| makeresults
| eval num = 1 
| eval var_type = typeof(num)
| eval num2 = tostring("num")
| eval var_type2 = typeof(num2)

Thanks

hi @LearningGuy,

as I said, you have to say what kind of string you want:

| makeresults
| eval num = 1 
| eval var_type = typeof(num)
| eval num2 = tostring(num,"commas")
| eval var_type2 = typeof(num2)

Ciao.

Hello @gcusello 

Sorry.. I tried again your last suggestion, but num and num2 still have type as "Number"
I expect num2 has "String" type after using   num2= tostring(num,"commas")  
Please suggest   Thanks again..

Hi @LearningGuy ,

As I said, using 1000 instead of 1 you have a string.

I don't know why with a different number you have a different type.

You eventually could to try:

| makeresults
| eval num = 1 
| eval var_type = typeof(num)
| eval num2 = tostring(num,"commas")." "
| eval var_type2 = typeof(num2)

Ciao.

Hi @LearningGuy ,

see at https://docs.splunk.com/Documentation/SCS/current/SearchReference/ConversionFunctions

and try

| makeresults
| eval num = 1
| eval var_type = typeof('num')
| eval num2 = tostring(num, "commas")
| eval var_type2 = typeof('num2')

Ciao.

Hi @LearningGuy,

what does it happen running:

| makeresults
| eval num = 1000
| eval var_type = typeof("num")
| eval num2 = tostring(num, "commas")
| eval var_type2 = typeof("num2")

Ciao.
