Comments

This information was supplemented by the Detached Solutions forum site. This routine is used to convert a floating-point number OP1 to a hex value in DE, but if the number in OP1 is greater than 9999, an error will occur. The same is thought to happen with decimal numbers; once discovered, more documentation will appear on this ROM call.
