Numeric cast that loses precision
Reports cast operations between primitive numeric types that may result in precision loss.
Such casts are not necessarily a problem but may result in difficult to trace bugs if the loss of precision is unexpected.
Example:
int a = 420;
byte b = (byte) a;
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
NumericCastThatLosesPrecision
Use the Ignore casts from int to char option to ignore casts from int
to char
. This type of cast is often used when implementing I/O operations because the read()
method of the java.io.Reader
class returns an int
.
Use the Ignore casts from int 128-255 to byte option to ignore casts of constant values (128-255) from int
to byte
. Such values will overflow to negative numbers that still fit inside a byte.
Here you can find the description of settings available for the Numeric cast that loses precision inspection, and the reference of their default values.
