chance.floating({ fixed: 7 })
chance.floating({ min: 0, max: 100 })

I wanted to use float or double as the method name but both are JS reserved words even though they aren't really used...

Return a random floating point number.

By default it will return a fixed number of at most 4 digits after the decimal.

Note: at most 4 digits. This because, unless we returned trailing zeroes (which aren't allowed on the JavaScript float) we can't guarantee 4 digits after the decimal. So if random chance comes back with 82383854.2000 then 82383854.2 is what will be returned.

To retrieve a set number of fixed digits after the decimal, provide it as an option.

chance.floating({ fixed: 7 });
=> -749512327.7447168

As with other number functions, can include a min and/or max.

chance.floating({ min: 0, max: 100 });
=> 31.9021

Or combine them.

chance.floating({ min: 0, max: 100, fixed: 8 });
=> 45.92367599
