Find the indicated values if the given changes are made in the indicated examples of this section.

In Example 3, change 1.1854 to 2.1854 and then find the required value.

Data from Example 3

Given log N = 1.1854, we find N as shown in the first line of the calculator display in Fig. 13.12. Therefore, N = 15.32

where the result has been rounded off. Because the given logarithm has four significant digits in its decimal part (1854), the antilogarithm is rounded to four significant digits. Since 10¹ = 10 and 10² = 100, we see that N = 10^1.1854 and is a number between 10 and 100.
