112. Find the limit of the absolute error of the number $a=$ $=1348$, if $\varepsilon_{a}=0.04 \%$.
Solution. Let's write the relative error boundary as $0.04\% = 0.0004$. To find the boundary of the absolute error of the number $a$, we will use the formula $\Delta a = |a| \varepsilon_{a}$, from which $\Delta a = 1348 \cdot 0.0004 = 0.539 \approx$ $\approx 0.5$. Therefore, $\Delta a = 0.5$ and the number can be written as: $a = 1348 \pm$ $\pm 0.5$.
