Frequently Asked Questions

What is a log2 function?

The log2 () function takes a single argument and returns a value of type double, float or long double. The log2 () function takes a single mandatory argument in the range [0, ∞]. If the value is less than zero, log2 () returns NaN (Not a Number). The log2 () function returns the base-2 logarithm of a number.

What is the base 2 logarithm?

For eyeball computations, the base 2 logarithm is close to equal to the base 10 logarithm plus the natural logarithm. For integers, you could loop on right bitshift, and stop when reached 0.

What is the syntax for returning logarithm of the argument?

Syntax for returning logarithm (base-10 logarithm) of the argument. result = log10 (x) The parameters can be of any data type like int, double or float or long double. Log () function returns value according to the following conditions are as follows: a) if x>1 then positive .. b) if 0<x<1 returns a negative value .. c) if x=1 then it returns 0 ..

What are the parameters of the logarithmic function?

Parameters: This function takes a value x, in the range [0, ∞] whose log value is to be found. Return Type: It returns the logarithmic value, as double, float or long double type, based on the following conditions: If x > 1: It returns the positive logarithmic value of x.
