Blitz inbuild functions much faster than thought

Again i stumbled over a little function for calculating distance without the need for a sqr-call. I always thought that these little functions would be computed faster, but here's the code:

Graphics3D 800,600

pivot_01 = CreatePivot()
pivot_02 = CreatePivot()

starttime = MilliSecs()

For i=1 To 10000

	PositionEntity pivot_01, Rand(-10000,10000),0,rand(-10000,10000)

	dist = EntityDistanceXZ(pivot_01,pivot_02)	
	
	;dist = EntityDistance (pivot_01,pivot_02)

Next

Text 0,0,MilliSecs() - starttime

Flip

;*********************************************************************************
;*** This calculate the 2d distance*distance on y axes 
;*** 
;*********************************************************************************
Function EntityDistanceXZ(Entity1,Entity2)
	p#=EntityX(Entity2)-EntityX(Entity1)
	q#=EntityZ(Entity2)-EntityZ(Entity1)
	Return (p*p)+(q*q)
End Function

That's happening when you "optimize" your code :-)
