val count_leading_zeros : nativeint -> int

count_leading_zeros n returns the number of most-significant zero bits before the most significant set bit in n. If n is 0, the result is the number of bits in n, that is 32 or 64, depending on the target.

val count_leading_zeros_nonzero_arg : nativeint -> int

Same as count_leading_zeros except if the argument is zero, then the result is undefined. Emits more efficient code.

val count_trailing_zeros : nativeint -> int

count_trailing_zeros n returns the number of least-significant zero bits before the least significant set bit in n. If n is 0, the result is the number of bits in n, that is 32 or 64, depending on the target.

val count_trailing_zeros_nonzero_arg : nativeint -> int

Same as count_trailing_zeros except if the argument is zero, then the result is undefined. Emits more efficient code.

val count_set_bits : nativeint -> int

count_set_bits n returns the number of bits that are 1 in n.
