Bug report¶

1. create a new Temporary Scratch Layer
2. add some fields
name: one
type: decimal number (real)
provider type: double
- length: 32
- precision: 30

name: two
type: decimal number (numeric)
provider type: numeric
- length: 20
- precision: 18

name: three
type: decimal number (decimal)
provider type: decimal
- length: 20
- precision: 18

name: four
type: decimal number (real)
provider type: real
- length: internally set to -1
- precision: internally set to -1

name: five
type: decimal number (double)
provider type: double precision
- length: internally set to -1
- precision: internally set to -1

3. add a new feature
4. add the value "0.01234567890123456789" into each field (length 22, precision 20)
5. save & check results
- one : 0.012345678901234568430878013601
- two : 0.012345678901234567
- three: 0.012345678901234567
- four : 0.012345678901234568
- five : 0.012345678901234568

6. When running "Refactor Fields", "Extract by Attribute" or others in Processing, the result is:
- one : 0.012345678901234568430878013601
- two : 0.012345678901234568
- three: 0.012345678901234568
- four : 0.01235 ["source field" shows, *precision gets smashed to 5*]
- five : 0.01235 ["source field" shows, *precision gets smashed to 5*]

Expected results¶

The output field should have the same precision as the input field.
