[JASS] Angle Calculations

[Cov3r70ps]

So, I currently have a function that rushes a unit along a given path, and as it passes other units, it will cause them to be knocked back, but I want all units to be pushed either perpendicularly to the path's left or the path's right depending on which side they fall on, but I'm confusing myself with the math involved. Currently I have:

Incorrect Math in Jass Code

set angle                   = Atan2((yTarget - yCaster),(xTarget - xCaster))
            
            if (RAbsBJ(angle - GetUnitFacing(.caster)) < 3.14159) then
                set angle   = GetUnitFacing(.caster) + (3.14159 / 2)
            else
                set angle   = GetUnitFacing(.caster) - (3.14159 / 2)
            endif

with angle being the value that I am passing into the knockback function. Does anyone see what I am doing wrong? I'm probably just confused somewhere along the way.

Atan2 returns values from -Pi to Pi.

Also: GetUnitFacing returns values in degrees (Blizzard sucks btw.).

Gag, but of course I'll have to fix that up when I get home. Thanks.
