 The \fImsatoshi\fR amount, if provided, is the amount that will be recorded as the target payment value\&. If not specified, it will be the final amount to the destination\&. If specified, then the final amount at the destination must be from the specified \fImsatoshi\fR to twice the specified \fImsatoshi\fR, inclusive\&. This is intended to obscure payments by overpaying slightly at the destination; the actual target payment is what should be specified as the \fImsatoshi\fR argument\&. \fImsatoshi\fR is in millisatoshi precision; it can be a whole number, or a whole number ending in \fImsat\fR or \fIsat\fR, or a number with three decimal places ending in \fIsat\fR, or a number with 1 to 11 decimal places ending in \fIbtc\fR\&.

 but a different 'msatoshi' or destination will fail; this prevents
 accidental multiple payments.
