leading_zeros
leading_zeros(x::Integer) > Integer
Number of zeros leading the binary representation of x
.
julia> leading_zeros(Int32(1))
31
Examples
The leading_zeros(x::Integer) > Integer
function in Julia returns the number of leading zeros in the binary representation of the given integer x
. Here are some examples:

Count leading zeros of an integer:
julia> leading_zeros(Int32(1)) 31
In this example, the binary representation of
Int32(1)
is00000000000000000000000000000001
. Since there are 31 leading zeros, the function returns31
. 
Leading zeros of a negative integer:
julia> leading_zeros(Int16(10)) 4
For a negative integer like
Int16(10)
, the leading zeros are also counted. The binary representation of10
in 16 bits is1111111111110110
, and there are 4 leading zeros.  Leading zeros of zero:
julia> leading_zeros(UInt8(0)) 8
When the input is zero, the function returns the total number of bits in the representation. For
UInt8(0)
, which has 8 bits, all of them are leading zeros.
It's important to note that the leading_zeros
function works only on integer types and returns the count of leading zeros in the binary representation.
