How do you find the logarithm of a number less than 1?
General procedure for determining logarithms of numbers less than 1: Determine the mantissa of the number as if it were between 1 and 10, using your L scale. Then subtract the characteristic for the number of places the decimal point of your actual number is to the left of the whole single digit number.
What is logarithm of number less than one?
The characteristic of the logarithm of any number greater than 1 is positive and is one less than the number of the digits to the left of the decimal point in the given number. If the number is less than one, then the characteristic is negative and is one more than the number of zeros to the right of the decimal point.
How do you find the Antilogarithm?
The antilog of any number is just the base raised to that number. So antilog10(3.5) = 10(3.5) = 3,162.3. This applies to any base; for example, antilog73 = 73 = 343.
What is the Antilogarithm of 1?
Value of AntiLog(1) = 10.00

Can the base of a log be less than 1?
If the base is less than 1, the logarithmic function is decreasing. The graph gets close to the y-axis when x is small, but with positive y values instead of negative ones.
How do you find the log of a decimal number greater than 1?
The characteristic of the logarithm of a number greater than 1 is positive and is one less than the number of digits in the integral part of the number. (ii) To find the characteristic of the logarithm of a number lying between 0 and 1: Since, log . 1 = -1 and log 1 = 0, hence the common logarithm of a number between .
What is antilogarithm with example?
The number whose logarithm is a given number. For example, the logarithm of 1,000 (103 ) is 3, so the antilogarithm of 3 is 1,000. In algebraic notation, if log x = y, then antilog y = x. If x is the logarithm of y, then y is the antilogarithm of x.
How do you find the log value of a log book?
Look up the logarithms of the two numbers you want to multiply. Use the method above to find the logarithms. For example, if you want to multiply 15.27 and 48.54, you would find the log of 15.27 to be 1.1838 and the log of 48.54 to be 1.6861. Add the two logarithms to find the logarithm of the solution.
What is antilogarithm Wikipedia?
antilogarithm (plural antilogarithms) (mathematics) The number of which a given number is the logarithm (to a given base). If x is the logarithm of y, then y is the antilogarithm of x. Synonym: antilog Antonym: logarithm.
Can value of log be greater than 1?
When you have a power function with base 0, the result of that power function is always going to be 0. And if those numbers can’t reliably be the base of a power function, then they also can’t reliably be the base of a logarithm. For that reason, we only allow positive numbers other than 1 as the base of the logarithm.
What is the log of a number greater than 1?
How do you calculate log and Antilogarithm?
The antilogarithm is simply the exponentiation! To calculate an antilog of any number y, you need to raise the logarithm base b (usually 10, sometimes e), to the power of y: x = log b -1(y) = b y. Since log and antilog are inverse functions, then this means that x = b y = b log bx, and y = log bx = log b(b y ).
How to calculate the antilog of a number?
Another way to calculate the antilog of a number is by using a calculator. Follow these steps to use this procedure: Step 1 – Determine the base. When you are calculating the antilog of a number, you always assume that it has the base ten. Step 2 – Calculate using the calculator. The answer is 154.6.
How do you write antilogarithm in exponential notation?
Define an antilogarithm in terms of a logarithm. The antilogarithm is the inverse function of a logarithm, so log(b) x = y means that antilog (b) y = x. You write this with exponential notation such that antilog (b) y = x implies b y = x.
How do you find the anti-logarithm of a number with base 10?
The Logarithms and Anti-Logarithms with base 10 can be converted into natural Logarithms and Anti-Logarithms by multiplying it by 2.303. To find the anti-logarithm of a number we use an anti-logarithmic table.
