Did you know?

10.2 Tokyo has introduced 3 new warnings for Delphi compilers:

Implicit integer cast with potential data loss from ‘<from>’ to ‘<to>’ W1071 IMPLICIT_INTEGER_CAST_LOSS Default: Off
Implicit conversion may lose significant digits from ‘<from>’ to ‘<to>’ W1072 IMPLICIT_CONVERSION_LOSS Default: Off
Combining signed type and unsigned 64-bit type – treated as an unsigned type W1073 COMBINING_SIGNED_UNSIGNED64 Default: On

Comment:

they were initially documented in less detail than the above table, and it keeps surprising me that you need to read employee blogs instead of the docwiki to keep current: [WayBack] New Warnings, Illegal Casts, and other Delphi compiler changes in 10.2 Tokyo.

Since then, documentation has improved to this:

Warning Identifier
IMPLICIT_INTEGER_CAST_LOSS W1071
IMPLICIT_CONVERSION_LOSS W1072
COMBINING_SIGNED_UNSIGNED64 W1073
