In 1 equals 0. No matter what the base of logarithm is, when n is equal to 1, the value is equal to 0. If the x power of a is equal to n, where a is greater than 0 and a is not equal to 1, then the number x is called logarithm with a base, and it is recorded that x is equal to logaN, where a is called the base of logarithm and n is called real number.

Characteristics of in 1

IN 1 is represented as a FB. If the input variable of FC is named S7200, then the input parameter of the subroutine LB0 system is named to allocate a temporary space for this input parameter, and the data length is Byte, and the address in the temporary area is 0. Mathematically, Ln 1 is equal to 0, and the answer can be obtained by using the idea of equation transformation. Let Ln 1 be equal to X. According to the transformation of logarithmic exponent, E X is equal to 65433.

The logarithm of the natural logarithm based on the constant e is called lnN, where n is greater than 0, and it is generally expressed as lnx. Logx is also commonly used in mathematics to represent natural logarithm. Because the logarithmic function logx grows slowly for large X, large-scale scientific data is compressed by logarithmic scale, and logarithm also appears in many scientific formulas, such as tsiolkovsky rocket equation, Fenske equation or Nernst equation.
