Join David Gassner for an in-depth discussion in this video Using math operators and the math package, part of Learning Go.
- Go supports the same set of mathematical operators…that work in other C style languages including…the usual math operators for addition,…subtraction, multiplication and division…and you also get all of the Bitwise operators…that are available in C and Java.…I've previously mentioned one of Go's interesting features,…that it doesn't implicitly convert Numeric types.…So that means that you can't take an integer value…and say, add it to a floating point value…without conversion.…
Take a look at this code.…I have one variable that's an integer…and another one that is a float…and then I try to add them together.…This code will result in an error,…invalid operation because the types are mismatched.…In order to add these values together,…I have to convert them so that they are of the same type…so now I've wrapped the integer value…in a conversion function.…I've turned it into a floating value…and now it matches the other floating value…and I can successfully add the two values together.…
For mathematical operations that go beyond…

- Storing ordered and unordered values
- Grouping related values in structs
- Programming conditional logic and loops
