CVLongIntfunction

Converts a double-precision floating-point number or eight-byte string to a LongInt variable

Syntax

Declare Function CVLongInt ( ByVal dbl As Double ) As LongInt

Declare Function CVLongInt ( ByRef str As Const String ) As LongInt

Parameters

Name		Description
`dbl`		A `Double` floating-point number with a binary copy of a `LongInt` variable stored in it.
`str`		A `String` at least eight bytes in length with a binary copy of a `LongInt` variable stored in it.

Return value

A LongInt variable holding a binary copy of the input variable.

Description

Returns a 64-bit LongInt value using the binary data contained in a Double, or a String of at least eight bytes in length. A value of zero (0) is returned if the string is less than eight bytes in length.

CVLongInt is used to convert 8-byte strings created with MKLongInt.

This function can also be used to convert 64-bit integer values from a memory or file buffer without the need for a Type structure. However, just as with the type structure, special care should be taken when using CVLongInt to convert strings that have been read from a buffer.

Remarks

Usage



result = CVLongInt( dbl )

result = CVLongInt( str )

Differences from QB

In QB an error occurs if the string passed is less than eight bytes in length.
QB did not support floating-point arguments.

Example

Dim ll As LongInt, s As String

s = "ABCDEFGH"

ll = CVLongInt(s)

Print Using "s = ""&"""; s

Print Using "ll = _&H&"; Hex(ll)
