Function std.numeric.entropy

Computes entropy of input range r in bits. This function assumes (without checking) that the values in r are all in [0, 1]. For the entropy to be meaningful, often r should be normalized too (i.e., its values should sum to 1). The two-parameter version stops evaluating as soon as the intermediate result is greater than or equal to max.

Prototypes

ElementType!Range entropy(Range)(
  Range r

if (isInputRange!Range);

ElementType!Range entropy(Range, F)(
  Range r,
  F max
)
if (isInputRange!Range && !is(CommonType!(ElementType!Range, F) == void));
