Ruby Integer bit_length function with example

The bit_length function in Ruby returns the number of bits in the value of int. Here number of bits signifies the bit position of the highest bit which is different from the sign bit. In case there is no such bit, zero is returned.

Syntax: number.bit_length

Parameter: The function takes the number and count its number of bits

Return Value: The function returns number of bits in the value of int.

Example #1:

# Ruby program of Integer bit_length function

# Initializing the numbers
num1 = 20
num2 = 8
num3 = 0
num4 = -1

# Prints the bit length
puts num1.bit_length
puts num2.bit_length
puts num3.bit_length
puts num4.bit_length

Output :

5
4
0
0

Example #2:

# Ruby program of Integer bit_length function

# Initializing the numbers
num1 = 2**1000
num2 = -100
num3 = 0
num4 = 2**3

# Prints the bit length
puts num1.bit_length
puts num2.bit_length
puts num3.bit_length
puts num4.bit_length

Output :

1001
7
0
4
