### Serve openLCA 2 Manual Locally with mdBook

Source: https://github.com/greendelta/openlca2-manual/blob/main/README.md

Navigate to the project directory and run the serve command to preview the manual locally. The --open flag automatically opens the manual in your default browser.

```bash
cd PATH/TO/openLCA2-manual
mdbook serve --open
```

### Build openLCA 2 Manual with mdBook

Source: https://github.com/greendelta/openlca2-manual/blob/main/README.md

Navigate to the project directory and run the build command to compile the manual.

```bash
cd PATH/TO/openLCA2-manual
mdbook build
```

### Ceiling Function for Integer Calculation

Source: https://github.com/greendelta/openlca2-manual/blob/main/src/parameters/dependent_parameter.md

Use the `ceil()` function to find the smallest integer not less than a given number. Useful for calculations involving discrete units like containers.

```openLCA
full_containers = ceil(total_volume / container_volume)
```

### Conditional Logic with IF Function

Source: https://github.com/greendelta/openlca2-manual/blob/main/src/parameters/dependent_parameter.md

Employ the `if(b;x;y)` function to return value `x` if condition `b` is true, otherwise return `y`. Ideal for setting results based on specific criteria.

```openLCA
result = if(condition; value_if_true; value_if_false)
```

### Calculate Total Cost with Production Volume and Wastage

Source: https://github.com/greendelta/openlca2-manual/blob/main/src/parameters/dependent_parameter.md

This formula calculates the total cost, considering production volume and wastage. It uses and() and if() functions to apply different cost calculations based on specified conditions.

```openLCA formula
total_cost = if(and(production_volume>500;wastage>30); (production_cost_per_unit - (production_volume+wastage));production_cost_per_unit*production_volume)
```
