如何用英语单词转换这个excel公式？

Question

can someone please translate this excel spreadsheet cell formula in english words ?

=ROUND(IF(F28 < 1568,2.5,IF(F28 < 2491,0.004873 * F28-5.142,0.02269*F28^0.7329)),2)

am creating a program based from that formula, but i don't understand which one will go first. atleast i understand this part IF(F28 is less than 1568) ...then what?

Answer 1

Start from the outer if statement and move inwards. The comma in the IF function separates the statements like :

boolean expression, true part, and false part

The following is the psuedo code of the above. All the Round are to two decimal places.

IF (F28 < 1568) THEN
  ROUND (2.5)
ELSE IF (F28 < 2491) THEN
  ROUND (0.004873 * F28 - 5.142)
ELSE
  ROUND (0.02269 * F28^0.7329)

Answer 2

If the value in cell F28 is less than 1568, then the value in this cell will be 2.5 rounded to 2 decimal places - ie 2.5

If the value in cell F28 is 1568 or more, but less than 2491, then the value in this cell will be: 0.004873 multiplied by [the value in cell F28 minus 5.142], rounded to 2 decimal places

Otherwise (ie the value in cell F28 is 2491 or more) the value in this cell will be: 0.02269 multiplied by [the value in cell F28 to the power of 0.7329], rounded to 2 decimal places

Answer 3

You will round the following in this order:

• Smaller than 1568 = 2.5
• Bigger than/Equal 1568 but smaller than 2491 = 0.004873 * F28-5.142
• Bigger than/Equal 2491 = 0.02269*F28^0.7329

Answer 4

Basically that means this:

IF F28 is smaller than 1568 then use 2.5
IF F28 is larger or equal to 1568 but smaller than 2491 then use 0.0004873 * F28 - 5.142
IF F28 is larger or equal to 2491 then use 0.02269 * F28^0.7329

Round the outcome to 2 digits.
