The Ruby Math.log2() method returns the base-2 logarithm of a given number.
Syntax
Math.log2(x)
Parameters
x |

Returns the base-2 logarithm of a given number.
If the x is negative, DomainError is thrown.
If the x is 0, it returns -Infinity.
Example:
In the example below, Math.log2() method is used to calculate the base-2 logarithm of a given number.
puts "Math.log2(1) = #{Math.log2(1)}"
puts "Math.log2(2) = #{Math.log2(2)}"
puts "Math.log2(10) = #{Math.log2(10)}"
puts "Math.log2(0) = #{Math.log2(0)}"
The output of the above code will be:
Math.log2(1) = 0.0 Math.log2(2) = 1.0 Math.log2(10) = 3.321928094887362 Math.log2(0) = -Infinity
