Use [the atof() function](https://www.cplusplus.com/reference/cstdlib/atof/) to convert a string representation of the float number to a float number. Screenshots of code are nearly worthless. If you want more help [**read the forum guidelines**](https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#posting-code-and-common-code-problems) to see how to **properly post code** and some information on how to get the most from this forum. **Use the IDE autoformat tool** (ctrl-t or Tools, Auto format) before posting code in code tags. Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information. **Please fix your original post.** --- _[View the full topic](https://forum.arduino.cc/t/array-float-conversion-problem/986958)._
