Add shorthand cast for DECFLOAT to simplify defining values in literals
-----------------------------------------------------------------------
Key: CORE-6060
URL: http://tracker.firebirdsql.org/browse/CORE-6060
Project: Firebird Core
Issue Type: Improvement
Components: Engine
Affects Versions: 4.0 Beta 1
Reporter: Mark Rotteveel
The literal support for DECFLOAT is limited to exact numeric literals of 20 or
more digits (eg 1.2345678901234567890), or for approximate numeric literals
(scientific notation, normally used for double precision) with a mantissa
greater than 308 or smaller than -308.
It would be helpful to introduce a shorthand cast, for example DECFLOAT'<signed
numeric string>', which would be equivalent to CAST('<signed numeric string>'
as DECFLOAT). This would be similar to the shorthand casts that exist for the
date/time types.
