    pub fn binomial<T: Integer + Clone>(n: T, k: T) -> T

Expand description

Calculate the binomial coefficient.

Note that this might overflow, depending on `T`. For the primitive integer types, the following n are the largest ones possible such that there will be no overflow for any k:

type | n
--- | ---
u8 | 10
i8 | 9
u16 | 18
i16 | 17
u32 | 34
i32 | 33
u64 | 67
i64 | 66

For larger n, consider using a bigint type for `T`.
