Convert Access Function To SQL

I'm going crazy trying to convert an Access Function to SQL.
From what I've read, it has to be done as a stored procedure.
I'm trying to take a field that is "minutes.seconds" and convert it to minutes.

This is what I have in Access:

Function ConvertToTime (myAnswer As Variant)
Dim myMinutes
myMinutes-(((((myAnswer * 100)Mod 100/100/0.6)+(CInt(myAnswer-0.4))))
ConvertToTime =(myMinutes)
End Function

When I tried to modify it in SQL:

CREATE PROCEDURE [OWNER].[PROCEDURE NAME] AS ConvertToTime
Function ConvertToTime(myAnswer As Variant)
Dim myMinutes
myMinutes = (((((myAnswer * 100)Mod 100)/100/0.6)+9CInt(myAnswer-0.4))))
ConvertToTime=(myMinutes)
End

I get an error after ConverToTime.
