EmmyMiao87 7ad72bbcb8 Enable decimalV2 cast to different precision (#2131)
The precision of cast function is useless. For example,
Query: select cast(10 as decimal(1,0));
Result: 10
Although numeric field is overflow, the numeric could be return.

So, the cast function from decimal(a,b) to decimal(c,d) could not be executed.
