Filled and issue:
https://github.com/tarantool/tarantool/issues/6531

In the issue added about INTEGER/UNSIGNED and size of prepared statement that is
affected by these changes.

Not sure if I got it right. At first we wanted to parse large numbers without
decimal point and exponent as DECIMAL if they are not fit for INTEGER, but we
decided to abandon this idea. Is that what you mean?

I added couple of tests with big numbers.

Added.

commit 2731dc7bf43486d2f0f251dc05b1f3f11855e9df

    sql: introduce literals for DECIMAL
    
    Part of #6356
    
    @TarantoolBot document
    Title: Literals for INTEGER, DECIMAL and DOUBLE
    
    The rules for parsing numeric values have changed:
    1) a value consisting of digits without decimal point and exponent will
    be parsed as INTEGER;
    2) a value consisting of digits and a decimal point will be parsed as
    DECIMAL;
    3) a value consisting of digits, containing an exponent and possibly
    containing a decimal point, will be parsed as DOUBLE.
