I am practising Julia on [techgig.com](http://techgig.com); there’s a ques name [Area of a Triangle](https://www.techgig.com/practice/question/area-of-a-triangle/eXlvOHVoR2E3L01RcFlXMFlRYi9RNUczaW56UW43dlFabSsyRXlIVEt1OGNuaFdNcngxaWw4bnloZW54UEZ2Sw==/1) in that I am getting an error

```julia
ERROR: LoadError: InexactError: Int64(Int64, 7.5)
Stacktrace:

```

It takes base and height as the input to get the area of the triangle in Int64 format, so after doing the multiplication (0.5 \* b \* h), I converted it to Int64 format. It gives an error for one test case where b=5 and height =3.

Code:

```julia
b,h = parse(Int64, readline()), parse(Int64, readline())
println(convert(Int64, 0.5*b*h))

```

Output for other test cases:

The error tells you that Julia can’t convert 7.5 into an integer (because it isn’t a whole number - makes sense).

In my opinion you should perform these calculations with Float64 as type.

But for the input given base =16 and height = 10, if I didn’t convert it to Int64, it will provide 80.0, and that’s not the expected output. So for that, I used convert()

Format the Float64 to match the spec instead of converting to an Int. Perhaps you can find examples here: [How to format float numbers in human-friendly format?](https://discourse.julialang.org/t/how-to-format-float-numbers-in-human-friendly-format/58209)
