Why did they do this: Sys_SetPhysicalWorkMemory( 192 << 20, 1024 << 20 ); //Min

Why did they do this:

Sys_SetPhysicalWorkMemory( 192 << 20, 1024 << 20 );   //Min = 201,326,592  Max = 1,073,741,824

Instead of this:

Sys_SetPhysicalWorkMemory( 201326592, 1073741824 );

    A neat property is that shifting a value << 10 is the same as multiplying it by 1024 (1 KiB), and << 20 is 1024*1024, (1 MiB).

    Shifting by successive powers of 10 yields all of our standard units of computer storage:

    So that function is expressing its arguments to Sys_SetPhysicalWorkMemory(int minBytes, int maxBytes) as 192 MB (min) and 1024 MB (max).
