I tried to write the most compact C code for this bool expression evaluation problem. Here is my final code: EDIT: deleted Here is the added negation handling: EDIT: test code added char *eval( char *expr, int *res ){ enum { LEFT, OP1, MID, OP2, RIGHT } state = LEFT; enum { AND, OR } … Read more
No, there’s no equivalent to Excel’s EVALUATE() in Google Sheets. There’s long history behind this one, see this old post for instance. If you’re just interested in simple math (as shown in your question), that can be done easily with a custom function. function doMath( formula ) { // Strip leading “=” if there if … Read more
You have to pass the variable as an argument to the pageFunction like this: const links = await page.evaluate((evalVar) => { console.log(evalVar); // 2. should be defined now … }, evalVar); // 1. pass variable as an argument You can pass in multiple variables by passing more arguments to page.evaluate(): await page.evaluate((a, b c) => … Read more
Evaluate might suit: http://www.mrexcel.com/forum/showthread.php?t=62067 Function Eval(Ref As String) Application.Volatile Eval = Evaluate(Ref) End Function
You are doing == which sorts out the types for you. 0 is an int, so in this case it is going to cast ‘e’ to an int. Which is not parsable as one and will become 0. A string ‘0e’ would become 0 and would match! Use === From PHP.net: Comparisons between strings and … Read more
If you want to evaluate a string expression use the below code snippet. using System.Data; DataTable dt = new DataTable(); var v = dt.Compute(“3 * (2+4)”,””);
