This is a variation of the FloatRound Playmaker action that only rounds down instead of to nearest.
Unity's rotation system is flawed because it uses 0-360 instead of 0-359. 0 and 360 are the same number on a full rotation scale. Float Clamping between 0-359 causes a 1/2 degree inaccuracy because 0 only gets to .501 before rounding to 1 and there is no rounding from 359 up to 0. Therefore 0 never gets a full degree for display.
To make a long story short, I needed a proper system to display angles for a submarine periscope. This 1/2 degree inaccuracy can cause a torpedo shot at 3500 meters to off by 10's of meters. By rounding the floats 0-359 down, 0 gets back its full 1 degree of range. Then it was just a matter of calibrating the periscope plus 1/2 degree.
Anyway, I thought someone might find this useful.
