Help us understand the problem. What are the problem?

More than 3 years have passed since last update.

@Q11Q

Access Excel 緯度 経度 130度45分15.001秒 S20度22分30秒を130.000 -20.0000に変換する関数

グローバル対応

正規表現を参照設定します。
各数字は正規表現で抜き出し、文字をカットする手法です。
また、西経、南緯はマイナス表記になります。
このため、文字列の最初か最後にW、Sが付けばマイナスにしています。
小数点以下が続くので倍精度Double形式です

''正負、NESWがある場合。正規表現を使用するので参照設定
Public Function DMStoSignGbl(str) As Double
Dim DegreeLng As Long, MinDbl As Double, SecDbl As Double
Dim Reg As RegExp: Set Reg = New RegExp
Dim M As Match, MC As MatchCollection, iM As Long, lSgn As Long
Reg.Global = True: Reg.MultiLine = True: Reg.IgnoreCase = False
Reg.Pattern = "(\-[0-9]{1,3}度|[0-9]{1,3}度)" '正負を想定して
Set MC = Reg.Execute(str)
If MC.Count > 0 Then Set M = MC(0)
DegreeLng = Abs(Replace(M.Value, "度", "", 1, 1, vbTextCompare))
If DegreeLng <> Replace(M.Value, "度", "", 1, 1, vbTextCompare) Then lSgn = Sgn(Replace(M.Value, "度", "", 1, 1, vbTextCompare))
Reg.Pattern = "(^S|S$|^W|W$)" 'S,Wが最初か最後にあれば符号はマイナス
If Reg.Test(str) = True Then lSgn = Sgn(True)
