# Percentage

is a crate trying to make using percentages in a safer way and easier to debug.
Whenever you see a Percentage, you will know what is being calculated, instead of having to revise the code.`percentage`

# Example

`//` You only need to import the `Percentage` struct
`use` `percentage``::`Percentage`;`
`//` Here we create the percentage to apply
`let` percent `=` `Percentage``::`from`(``50``)``;`
`println!``(``"``{}``"``,` percent`.``value``(``)``)``;` `//` Will print '50'
`//` We can apply the percent to any number we want
`assert_eq!``(``15``,` percent`.``apply_to``(``30``)``)``;`
`println!``(``"`50% of 30 is: `{}``"``,` percent`.``apply_to``(``30``)``)``;` `//` Will print '50% of 30 is: 15'
`//` If you need to use floating points for the percent, you can use `from_decimal` instead
`let` percent `=` `Percentage``::`from_decimal`(``0.``5``)``;`
`assert_eq!``(``15.``0``,` percent`.``apply_to``(``30.``0``)``)``;`
`println!``(``"`50% of 30.0 is: `{}``"``,` percent`.``apply_to``(``30.``0``)``)``;` `//` Will print '50% of 30.0 is: 15.0'
