Learn about the different kinds of built-in functions that Julia provides and how to use them.
- [Instructor] Just like some other popular languages, … Julia has some built-in useful functions. … So let's take a look at some of those in this example. … Go ahead and open up the builtin_start file … and let's begin by looking at some of the math functions. … So you can use the round function to round numbers … in a variety of ways so I'll go ahead and just use … the round function to round this number … and then we can print that out. … I can also specify a rounding direction. … So for example, I can write x = round and then same number … but now I can specify a direction. … So you can see I can choose round down, … round from zero, so on. … We'll go ahead and choose round up and then print that out. … I can use the floor and ceiling functions … to perform rounding operations as well. … So if I have a value like this, … I can print out the floor result of that, … and I can also print out the ceiling of that, … which will round up, … and I can use a function like absolute value to print out …
