returns 3.
- Note: When the object is not found, result is undefined.
- IndexOf[ <Object>, <List>, <Start Index> ]
- Same as above, but the search starts at given index.
- Examples:
IndexOf[5, {1, 3, 5, 2, 5, 4}, 3]
returns 3.IndexOf[5, {1, 3, 5, 2, 5, 4}, 4]
returns 5.IndexOf[5, {1, 3, 5, 2, 5, 4}, 6]
returns undefined.
- IndexOf[ <Text>, <Text> ]
- Specifies the position at which the short text appears for the first time in the whole text.
- Example:
IndexOf["Ge", "GeoGebra"]
returns 1.
- IndexOf[ <Text>, <Text>, <Start Index> ]
- Same as above, but the search starts at given index.
- Example:
