[求助]求高手帮助修改一下代码

这是一个工程测量平差代码，调试时出现错误。麻烦各位高手查看并修改一下，小弟在这里不胜感激。

Public Const pi = 3.14159265359
Public Function DEG(n As Double)
Dim A As Double, B As Double, C As Double, D As Double, E As Double, F As Double, G As Double, KA As Double
D = Abs(n) + 0.000000000000001
F = Sgn(n)
A = Int(D)
B = Int((D - A) * 100)
C = D - A - B / 100
DEG = F * (A + B / 60 + C / 0.36) * pi / 180
End Function
