Re: [AD] float math function inconsistencies

[Nick Trout <chinbillybilbo@xxxxxxxxxx>]

Well a lot of the ones I changed are double functions which are passed floats which then set a float value. So surely the precision would be lost in most cases?

It would be good to comment where double is necessary. Often it is important the order of float operations to try and maintain precision.

It definitely shouldn't be all double. In spots where it makes sense, sure, but not everywhere.
