yaml - How to cast value to long in yaml fil

Question

How can I cast a value to long in yaml file. I have tried the way as like float like this:

value: !!long 3000

but it says that class not found long. I have tried Long as well.

Answer 1

long isn't a supported YAML type, so the short answer is, you cannot perform the cast in question.

As a work around, string or binary representations would work. Binary is more machine friendly, but strings are typically easier for people to check & edit by hand.
