Reduce a number down to a static set of numbers

问题

Okay, so I have a Google Sheet that I need to reduce a number down to a specific set of 4 numbers. Then count how many times those numbers occur.

For example:

The numbers it breaks down to: 1, 2, 3, 4

Disregard their individual values other than for the purpose of being broken down.

Now take the number 17.

Count+Add 1, 2, 3, 4, 1, 2, 3 = 7 r1

Take number 12

Count+Add 1, 2, 3, 4, 1 =  r1

The remainder is rounded DOWN

So, basically, it breaks down Cell A1 into a count of how many sequences it takes to reach the total of the number in A1, rounddown.

回答1:

try:

=ARRAYFORMULA(COUNTA(IFERROR(QUERY(MMULT(TRANSPOSE((
 ROW(INDIRECT("A1:A"&A2*COUNTA(SPLIT(B2, ","))))<=TRANSPOSE(
 ROW(INDIRECT("A1:A"&A2*COUNTA(SPLIT(B2, ","))))))*TRANSPOSE(
 SPLIT(QUERY(B2&IF(ROW(INDIRECT("A1:A"&A2))<>"", ",")
 ,,9^9), ","))), SIGN(TRANSPOSE(
 SPLIT(QUERY(B2&IF(ROW(INDIRECT("A1:A"&A2))<>"", ",")
 ,,9^9), ",")))), "where Col1 <="&A2, 0))))

Seems odd but...

Your sequence adds to 10, so your number tens place and above times 4 is your first element. Then if the ones digit is between 6 and 9 you add 3, 3 to 5 add 2, or 1 to 2 add 1. There is probably a more elegant formula that this...

=(INT(A1/10)*4)+IF(MOD(A1,10)>0,1,0)+IF(MOD(A1,10)>3,1,0)+IF(MOD(A1,10)>5,1,0)
