Excel formula for rounding

I have two values on an excel spreadsheet Cell A1 is equal to $12.56 and cell B1 is equal to $12. I need a formula that will compare B1 to A1 and give me a message "OK" if the amounts tie. The amounts will generally not tie due to round ding. Can the formual accomodate a rounding difference of 20 and still get the OK message? Below is the formula that I am using. Due to the .56 difference, its giving me the message "This total does not tie to A1"

IF(B1=A1,"OK","This total does not tie to A1"

MROUND should help!
=MROUND(A1,0.2)

I think you want:
=IF(MROUND(B1,0.2)=MROUND(A1,0.2),"OK","This total does not tie to A1")

Open in new window

If you want to get fancy and make the message dynamic too you can use this (which when copied down a column will give the correct A1, A2, etc.):
=IF(MROUND(B1,0.2)=MROUND(A1,0.2),"OK","This total does not tie to "&SUBSTITUTE(CELL("address",A1),"$",""))

if you want to check to see if A1 is within a value of A2 then use this

=if(ABS(A1-A2) < 'your value' ,"YES","NO")

I want the amount to be OK if the difference in A1 and B2 is $100.00 or less.

Then is my equation use 100 for 'your value' and change it to a <= sign. The use of ABS will ensure that it doesn't matter if A1 > A2 or vice versa
