Typmod handling for functions expression with numeric.

[Yvinayak07]

Issue

In resolve_numeric_typmod_from_exp we missed the handling for typmod calculation for some mathematical functions in function expression like ROUND(), POWER(), CEILING(), FLOOR(), SIGN(), ABS(), DEGREES(), RADAINS(), SCOPE_IDENTITY(), IDENT_SEED(), IDENT_INCR(), IDENT_CURRENT().

2. Changes made to fix the issues

Added handling for ROUND(), POWER(), CEILING(), FLOOR(), SIGN(), ABS(), DEGREES(), RADAINS(), SCOPE_IDENTITY(), IDENT_SEED(), IDENT_INCR(), IDENT_CURRENT() mathematical functions in T_FuncExpr node
