operator << abstract method Null safety

int operator <<(
  1. int shiftAmount

Shift the bits of this integer to the left by shiftAmount.

Shifting to the left makes the number larger, effectively multiplying the number by pow(2, shiftAmount).

There is no limit on the size of the result. It may be relevant to limit intermediate values by using the "and" operator with a suitable mask.

It is an error if shiftAmount is negative.


print((3 << 1).toRadixString(2)); // 0011 -> 0110
print((9 << 2).toRadixString(2)); // 1001 -> 100100
print((10 << 3).toRadixString(2)); // 1010 -> 1010000


int operator <<(int shiftAmount);
