Function num_integer::binomial [−][src]
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
.
