Gauss is considered one of the most outstanding mathematicians in history, known as the "Prince of Mathematics." There is a calculation formula defined by Gauss, where $\left[x\right]$ represents the largest integer not exceeding $x$. For example, $\left[4.8\right]=4$, $\left[-0.8\right]=-1$. It is defined that $\{x\}=x-\left[x\right]$, for example, $\{1.5\}=1.5-\left[1.5\right]=0.5$. Therefore, $\{3.8\}+\{-1.7\}-\{1\}=\_\_\_\_\_\_$.
