如何检查位值是否等于1？

// Here we will store our bit

string bit;

// Unsigned integer that will be converted

uint hex = 0xfffffffe;

// Perform conversion and store our string containing bits

string str = uint2bits(hex);

// Print all bits "11111111111111111111111111111110"

Console.WriteLine(str);

// Now get latest bit from string

bit = str.Substring(31, 1);

// And print it to console

Console.WriteLine(bit);

// This function converts uint to string containing bits

public static string uint2bits(uint x) {
    char[] bits = new char[64];
    int i = 0;
    while (x != 0) {
        bits[i++] = (x & 1) == 1 ? '1' : '0';
        x >>= 1;
    }
    Array.Reverse(bits, 0, i);
    return new string(bits);
}

__kernel void hello(global read_only uint* param) {

/*

Do something with "param"

...

*/

int bit;
int index = 31;

/*

Store bit value ("0" or "1") at variable "bit"

...

*/

if (bit == 1) {

// ...

} else {

// ...

}

// Or maybe something more easy to check a bit value at "index" in "param" ... ?

}
