Method `<<()

Method `<<

int `<<(int arg1, int(0..) arg2)
mixed `<<(object arg1, int(0..)|object arg2)
mixed `<<(int arg1, object arg2)
mixed `<<(float arg1, int(0..) arg2)

Description

Left shift.

Every expression with the << operator becomes a call to this function, i.e. a<<b is the same as predef::`<<(a,b).

If arg1 is an object that implements lfun::`<<(), that function will be called with arg2 as the single argument.

If arg2 is an object that implements lfun::``<<(), that function will be called with arg1 as the single argument.

If arg1 is a float and arg2 is a non-negative integer, arg1 will be multiplied by 1<<arg2.

Otherwise arg1 will be shifted arg2 bits left.
