The log2() function in Ruby returns the base 2 logarithm value of X.
Syntax: Math.log2(X)
Parameter: The function takes one mandatory parameter X whose base 2 logarithm value is to be returned.
Return Value: The function the base 2 logarithm value of X.
Example 1:
# Ruby program for log2() function # Assigning values val1 = 213 val2 = 256 val3 = 27 val4 = 100 # Prints the value returned by log2() puts Math.log2(val1)
puts Math.log2(val2)
puts Math.log2(val3)
puts Math.log2(val4)

Output:
7.734709620225838 8.0 4.754887502163468 6.643856189774724
Example 2:
# Ruby program for log2() function # Assigning values val1 = 21 val2 = 2 val3 = 19 val4 = 121 # Prints the value returned by log2() puts Math.log2(val1)
puts Math.log2(val2)
puts Math.log2(val3)
puts Math.log2(val4)
