Join Kevin Skoglund for an in-depth discussion in this video Improve float formatting, part of Easy PHP Projects: Measurement Conversion.
- In this movie, we will write a custom .php function…that can improve the formatting…of our floating point numbers.…Open up your functions.php file,…and in there, right under optionize,…we're going to add a new function.…One of the nice things about adding it as a function…is that then it becomes a function…that we can pull and reuse in other projects, if we need to.…So let's call this function float_to_string,…and that's going to be our custom function…that will allow us to convert a floating point number…into a string in the way that we want.…
So let's have as an argument the float…that we're going to pass in, and inside here…we're going to use that number format…as a basis that we saw earlier.…The number format is going to take…a couple of arguments.…The first one is going to be the float itself.…The second one is going to be the precision.…That's going to be a number that tells us…how many decimal places we want to have.…Now, we could have that as a hard-coded value…in here, but I'm going to go ahead…and make that flexible by making it…
Along the way, series designer Kevin Skoglund introduces coding strategies, refactoring techniques, and useful skills including dynamically generating form select-option values and formatting decimal numbers and scientific notation.
