storage

Gets the number of bits used to hold number, e.

g. if number is 4, 3 bits are needed.

Example: Compute the numbers of bits used to store a given number:

public static int main (string[] args) {
	// Output: ``3`` (4 => 100)
	uint bits = Bit.storage (4);
	print ("%u\n", bits);

	// Output: ``3`` (5 => 101)
	bits = Bit.storage (5);
	print ("%u\n", bits);

	// Output: ``4`` (8 => 1000)
	bits = Bit.storage (8);
	print ("%u\n", bits);

	return 0;
}

valac --pkg glib-2.0 GLib.Bit.storage.vala

Parameters:

number

a uint

Returns:

the number of bits used to hold number
