The number is called e, and it is approximately equal to 2.718.
There are an infinite number of irrational numbers. Here are some: e (the base for natural logarithms), pi, sqrt(2), sqrt(3), sqrt(5), square root of any number that is not a perfect square: perfect squares are 12 22 32 42 52 etc. which equals 1 4 9 16 25 ..... natural logarithm of any rational number (greater than zero) will be irrational. but not 1, since ln(1) = 0, which is not irrational. Note the logarithm of a negative number is a complex number, and the logarithm of zero is negative infinity.
Usually it is, yes. Of course, in some special cases the result of taking a logarithm is rational - such as taking the base-10 logarithm of 100.
Because it's an irrational number, and that's what "irrational" means. There are lots of other irrational numbers, like the base of the natural logarithm e or the square root of 2.In fact, there are more irrational numbers than rational numbers. A lot more.Infinitely more, even. There are an infinite number of rational numbers, but the infinite number of irrational numbers is a higher infinity than the infinity of rational numbers.
An irrational number.
Rational.

ln x is the natural logarithm of x, that is the logarithm to base e where e is euler's number (an irrational number that starts 2.71828...). If y = ln x then x = ey

A logarithm is the exponent to which a number called a base is raised to become a different specific number. A common logarithm uses 10 as the base and a natural logarithm uses the number e (approximately 2.71828) as the base.
In the Steinhart-Hart equation, "ln" stands for the natural logarithm function. The natural logarithm is denoted by "ln" to distinguish it from the common logarithm, which is typically denoted by "log".
Pi (used to calculate the circumference and area of a circle) Phi (the so-called 'golden ratio', and its inverse) e (the base of the natural logarithm) the square roots of 2 and 5
That is a logarithm to the base "e", where "e" is a number that is approximately 2.718.
A number for which a given logarithm stands is the result that the logarithm function yields when applied to a specific base and value. For example, in the equation log(base 2) 8 = 3, the number for which the logarithm stands is 8.
