How to get a zero

What's the best way to obtain a zero value on PLAYER_CMOVESPEED#
It starts doing this 1.-e1234 things after a while.

Should floats just be avoided?

;My Code
Graphics3D 640, 480, 0, 2

CAM = CreateCamera()
MoveEntity CAM, 0, 80, 0
TurnEntity CAM, 90, 0, 0



Global PLAYER_MOVESTATE
Global PLAYER_MOVESPEED# = .75
Global PLAYER_CMOVESPEED#
Global PLAYER_MOVEACC# = .01

Global PLAYER_MOVEDIRECTION



Global PLAYER_MESH
PLAYER_MESH = CreateCube()
EntityFX PLAYER_MESH, 1

Create_Grid(32)


Repeat

	
	Move_Player()
	
	DebugLog PLAYER_CMOVESPEED#
	
	RenderWorld()
	Text 0, 0, "Speed: " + PLAYER_CMOVESPEED#
	Text 0, 20, "Move State: " + PLAYER_MOVESTATE
	Flip 

Until KeyHit(1)
End



Function Move_Player()
	If KeyDown(17) Then
		move = 1
		PLAYER_MOVEDIRECTION = 1
	EndIf
	
	If KeyDown(31) Then
		move = 1
		PLAYER_MOVEDIRECTION = -1
	EndIf
	
	
	If KeyDown(30) Then
		turn = 1
	EndIf
	
	If KeyDown(32) Then
		turn = -1
	EndIf
	
	If move = 1 Then
		If PLAYER_MOVEDIRECTION = 1 Then
			PLAYER_CMOVESPEED# = PLAYER_CMOVESPEED# + PLAYER_MOVEACC#
			If PLAYER_CMOVESPEED# > PLAYER_MOVESPEED# Then PLAYER_CMOVESPEED# = PLAYER_MOVESPEED#
		Elseif PLAYER_MOVEDIRECTION = -1
			PLAYER_CMOVESPEED# = PLAYER_CMOVESPEED# - PLAYER_MOVEACC#
			If PLAYER_CMOVESPEED# < -PLAYER_MOVESPEED# Then PLAYER_CMOVESPEED# = -PLAYER_MOVESPEED#
		EndIf
	Else
		If PLAYER_CMOVESPEED < 0 Then
			PLAYER_CMOVESPEED# = PLAYER_CMOVESPEED# + PLAYER_MOVEACC#
		ElseIf PLAYER_CMOVESPEED > 0
			PLAYER_CMOVESPEED# = PLAYER_CMOVESPEED# - PLAYER_MOVEACC#
		EndIf
	EndIf
	
	If PLAYER_CMOVESPEED# <> 0 Then
		MoveEntity PLAYER_MESH, 0, 0, PLAYER_CMOVESPEED#
	EndIf

	TurnEntity PLAYER_MESH, 0, turn, 0
