How to define the value data type in a Yaml file?

About

In Yaml, you indicates the data type in the way you write the value: 

values:
  - world # varchar
  - "1" # the quotes indicates a varchar
  - '1' # the quotes indicates a varchar
  - 1 # integer
  - 1.0 # double, float, not a numeric/decimal
  - 2020-10-01 01:00:00 # timestamp/datetime
  - 2020-10-01 # date
  - 10:12:20 # time
  - true # boolean
  - false # boolean

Decimal/Numeric Support

Yaml by default do not support decimal/numeric but we transform them from string, integer or double/float
