InfluxDB Flux: type conflict: int != float

In a Flux query I was writing I wanted to negate the fetched values using a map function to multiply each value by -1:

map(fn: (r) => ({ _value: r._value * -1 }))

To my surprise this yielded an error:

type conflict: int != float

Took me a few Google Search Coupons to realize the error got trigger not by the type of the _value, but by the -1 in there. The solution therefore is really simple: don’t multiply by an integer (e.g. -1) but multiply by a float (e.g. -1.0); like so:

map(fn: (r) => ({ _value: r._value * -1.0 }))

😅

Did this help you out? Like what you see?
Thank me with a coffee.

I don't do this for profit but a small one-time donation would always put a smile on my face. Thanks!
