LongLong

Converts data into data of type longlong. There are two syntaxes.

To

Use

Combine two unsigned long values into a longlong value

Syntax 1

Convert a string whose value is a number into a longlong or obtain a longlong value stored in a blob

Syntax 2


Syntax 1: For combining longs

Description

Combines two unsigned longs into a longlong value.

Syntax

LongLong ( lowword, highword )

Argument

Description

lowword

An UnsignedLong to be the low word in the longlong

highword

An UnsignedLong to be the high word in the longlong


Return value

LongLong.

Returns the longlong if it succeeds and -1 if an error occurs. If any argument's value is null, LongLong returns null.

Usage

Use LongLong for passing values to external C++ and Java functions.

Examples

These statements convert the UnsignedLongs lLow and lHigh into a long value:

UnsignedLong lLow      //Low long 32 bits
UnsignedLong lHigh     //High long 32 bits
longlong LLValue       //LongLong value 64 bits
 
lLow = 1234567890
lHigh = 9876543210
LLValue =  LongLong(lLow, lHigh)
MessageBox("LongLong Value", LLValue)

Syntax 2: For converting strings and blobs

Description

Converts a string whose value is a number into a longlong or obtains a longlong value stored in a blob.

Syntax

LongLong ( stringorblob )

Argument

Description

stringorblob

The string you want returned as a longlong or a blob in which the first value is the longlong value. The rest of the contents of the blob is ignored. Stringorblob can also be an Any variable containing a string or blob.


Return value

LongLong.

Returns the value of stringorblob as a longlong if it succeeds and 0 if stringorblob is not a valid PowerScript number or if it is an incompatible datatype. If stringorblob is null, Long returns null.

Usage

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 LongLong function.

Examples

This statement returns 216789987654321 as a longlong:

LongLong("216789987654321")

After assigning blob data from the database to lb_blob, the following example obtains the longlong value stored at position 20 in the blob:

longlong llb_num
llb_num = LongLong(BlobMid(lb_blob, 20, 4))

For an example of assigning and extracting values from a blob, see Real.
