Hi, Arduino 1.8.13, Board Arduino Mega 2056. I need to set individual bits in a int32 (long) value. For that, I use the left-shift like 1 << 30 which is expected to shift a 1 bit into the msb-1 position in the 32 bits value. The result was 0 (zero). I tested the command and found out that it wi…

[image] samtal: I use the left-shift like 1 << 30 which is expected to shift a 1 bit into the msb-1 position in the 32 bits value. Just use 1L << 30 or 1UL << 30. Expressions (and so numbers) are evaluated as 16 bit by default, if the operand is given an explicit type, it is used.

Left Shift more than 15 bits fails?
