math.exp2
Available inall subroutines.
Computes the value of 2 raised to the x
power (e.g., 2ˣ).
This is equivalent to shifting the integer 1 to x
bits to the left
(e.g., 2^x == 1 << x
), except that math.exp2
is only for FLOAT
type values.
Example
vcl_deliver { declare local var.foo FLOAT; set var.foo = math.exp2(32); # result: 4294967296.0}
