Varible and ValueLevel length for flaotvalues

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.
