How do you find the log of 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.
Can you take the log of a number less than 1?
A logarithm tells the power of 10 that number is (for example, log 1000 is 3, because 10^3 is 1000). If you take the log of a number less than 1, you would have to have a decimal number because only a decimal, fraction, or negative can produce a number smaller than the original.
What is the natural log of a number less than 1?
The natural logarithm of any number less than 1 is a negative number. For example, the natural logarithm of 0.5 is −0.693147, or e−0.693147=0.5.
How do you find the value of log 1?
As we know, any number raised to the power 0 is equal to 1. Thus, 10 raised to the power 0 makes the above expression true. This will be a condition for all the base value of log, where the base raised to the power 0 will give the answer as 1. Therefore, the value of log 1 is zero.
How do you calculate antilog and log?
Logarithmic Laws and Properties log b x y = p + q = log b x + log b y. The division of the two numbers is the antilog of the difference of logarithm of the two numbers. The base should be the same for both the numbers. a p = x = b q, and a r = b.
How do you find the log of a number?
The power to which a base of 10 must be raised to obtain a number is called the common logarithm (log) of the number. The power to which the base e (e = 2.718281828…….)…CALCULATIONS INVOLVING LOGARITHMS.
| Common Logarithm | Natural Logarithm |

| log = log x1/y = (1/y )log x | ln = ln x1/y =(1/y)ln x |
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 log of a number?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.
What is the value of log 1 *?
0
log 1 = 0 means that the logarithm of 1 is always zero, no matter what the base of the logarithm is. This is because any number raised to 0 equals 1. Therefore, ln 1 = 0 also.
