No.  The word is usually capitalized when used as
an adjective, e.g. Boolean logic, but not so much
when used as a noun, and especially not when used
as the name of a data type in a programming language
unless the language capitalizes the names of all
(or all basic) types.  See e.g.

Yes.  If the data type is capitalized, then the
adjective that distinguishes elements of that data
type should also be capitalized.
