What's Wrong?

conv() with float value as input parameter leads to incorrect result

What You Expected?

float value or other illegal values are banned from conv() function

How to Reproduce?

Just execute

create table test_tb(int_1 int, float_2 float);

insert into test_tb values(1, 1.464868);

select conv(float_2,10,2),float_2 from test_tb;

The result "0" is incorrect, it should be like "0 01111111 01110111000000011001011"

BTW, I suggest that the conv() prohibits floating-point numbers as input parameters

Anything Else?
