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

result = Cvlongint( dbl )
result = Cvlongint( str )

A Double floating-point number with a binary copy of a Longint variable stored in it.
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.

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.

Dim ll As LongInt, s As String
ll = CVLongInt(s)
Print Using "s = ""&"""; s
Print Using "ll = _&H&"; Hex(ll)
