Answer 1

Your data type of the column must be decimal and must have precision and scale. The precision represents the number of significant digits that are stored for values, and the scale represents the number of digits that can be stored following the decimal point.

Example

paypalAmount DECIMAL(10,2)

by default the value of precision is 10 and the scale is 0. If the value of your scale is 0 then it will not have decimal value and causing to round the value you inserted.
