Binary ** is the exponentiation operator. Note that it binds even more tightly than unary minus, so -2**4 is -(2**4), not (-2)**4. Note also that ** has right associativity, so:
$e = 2 ** 3 ** 4;
evaluates to 2 to the 81st power, not 8 to the 4th power.
The * (multiply) and / (divide) operators work exactly as you might expect, multiplying or dividing their two operands. Division is done in floating-point mode, unless integer mode in enabled (via use integer).
