Varible and ValueLevel length for flaotvalues

Define-XML is based on ODM-1-3-1. So you should check the ODM-1-3-1 specification too.
There it is very clear:

Hi Team,

Please confirm how we can display the length for data types ‘float’ and ‘integer’ at the variable level and value level.

data_type=‘Flaot’

For example Variable AVAL :

one of the AVAL values has 12.3456789123,

Varible level : Length = 8 . Siginificant_Digits = 10

Value Level : Length = 13 , Significant_Digits = 10

data_type= Integer

For example Variable AVAL :

one of the AVAL value has 123456789123,

Varible level : Length = 8.

Value Level : Length = 12.

Please confirm do we need to display the length 8 for data types float and integer at value level or actual digits length have to display.

Thank you,

Rajasekhar.
