Converts the value of a string to an integer or obtains an integer value that is stored in a blob.
Integer ( stringorblob )
Argument |
Description |
|---|---|
stringorblob |
A string whose value you want returned as an integer or a blob in which the first value is the integer value. The rest of the contents of the blob is ignored. Stringorblob can also be an Any variable containing a string or blob. |
Integer. Returns the value of stringorblob as an integer if it succeeds and 0 if stringorblob is not a valid number or is an incompatible datatype. If stringorblob is null, Integer returns null.
To distinguish between a string whose value is the number 0 and a string whose value is not a number, use the IsNumber function before calling the Integer function.
This statement returns the string 24 as an integer:
Integer("24")
This statement returns the contents of the SingleLineEdit sle_Age as an integer:
Integer(sle_Age.Text)
This statement returns 0:
Integer("3ABC") // 3ABC is not a number.
This statement (PocketBuilder only) returns a decimal value for a hexadecimal string :
Integer("0x3ABC") // Returns 15036.
This example checks whether the text of sle_data is a number before converting, which is necessary if the user might legitimately enter 0:
integer li_new_data
IF IsNumber(sle_data.Text) THEN
li_new_data = Integer(sle_data.Text)
ELSE
SetNull(li_new_data)
END IF
After assigning blob data from the database to lb_blob, this example obtains the integer value stored at position 20 in the blob:
integer i
i = Integer(BlobMid(lb_blob, 20, 2))
