Fun Bash Script: numerical calculation, bash script Numerical Calculation 6th articles The mathematical operations in Bash are not as simple as other languages, because Bash treats all variables as strings, so a = 1 + 2, a is not equal to 3, but equal to string 1 + 2. There are several solutions to solve this problem.OPERATOR [] a=2b=3c=$[a+b]d=$[a-b]e=$[a*b]f=$[a/b]g=$[a%b] $ Is only the meaning of the
Characteristics: Strong data correlation; Often exhibit poorer memory access locality Too little processing for a single vertex Along with the change of parallelism in the calculation process Large graph calculation mainly includes two kinds: A real-time graph database based on traversal algorithm, such as NEO4J, Orientdb, Dex and Infinite graph; Based on the vertex-centric parallel engine, such as G
Why do the formulas in Excel sometimes calculate inaccuracies and calculate error values? In general, the use of formula functions, as long as the attention to two aspects of the problem, should not have any problems. One is to use a pair function. Each function has its own name, and each function has its own calculation function. Therefore, the use of the name of the function is to ensure that the calculation
