We can’t just round to the “nearest” .45 or .95 value.
In fact, the first step is to roundupto the nearesthalfdollar (.50).
The second step is to subtract 5 cents ($0.05).
For example, $4.31 will become $4.50, and $5.72 will become $6.00.
Importantly, if a price already ends in .00 or .50, it will remain unchanged (i.e.
a price of $4.00 or $4.50 is not affected).
Once rounded, the formula simply subtracts 0.05 to get a .45 or .95 result.
CEILING works like theMROUND function, but CEILINGalways rounds up.
