Question for Stall folks (Economics)

In study session 4 page 78 the text states that the loss from triangular arbitrage going in the opposite direction is 2,144. I keep getting 2,132 as an answer. Has anyone else got this?

Converting $1000000 to pounds @ .6237 pounds per dollar - 623700 Converting 623700 pounds to yen at 187.98 yen per pound - 117243126 yen Converting that to dollars @ .008511 dollars per yen - 997856.24 This gives a loss of 2144

I see it’s a rounding error. I divided 1mm by 1.6033 to get 623,713.59.

Thanks, alot
