Purpose of returning by const value? [duplicate]

Seeking clarification on apparent contradictions regarding weakly typed languages

$foo = "123" + "456"; # $foo = 579
$bar = substr($foo, 2, 1); # $bar = 9
$bar .= " lives"; # $bar = "9 lives"
$foo -= $bar; # $foo = 579 - 9 = 570

Cast to int vs floor

Why do you think they will have the same result?
float foo = (int)(bar / 3.0) //will create an integer then assign it to a float
float foo = fabs(bar / 3.0 ) //will do the absolute value of a float division
bar = 1.0
foo1 = 0;

Shell equality operators (=, ==, -eq)

$ [ "$a" -eq foo ]; echo "$?" # wrong
