Text and Number Format on Excel

i have question that when i want to compare between a1= 1.3 b1= 3 and a2= 1.3 b2= 2 on excel

for example =IF(a1>a2,"Yes",IF(a1=a2,IF(b1>b2,"Yes","No"),"no"))

first time it's okay but then i changed value from b1 =1 it changed to "no" then i changed it back to b1= 3 it's still "no"

i think it concern on format in the cell

another concern is if i use like 1.3.1 compare to 1.3.1.2 it doesn't have any problem

but when i use only 1.3 (one decimal point) it alway have problem

it's hard to explain you should try to compare between x.x and x.x.x

also if you have a good another VBA code to compare version number

thank you please tell me i want to study about it

it like 1 decimal point excel see as number but many decimal point excel see as text

how do i fix this (i have try change to text format but it work 1 time after you change value in cell it's go back to error.)

Due to my english is poor. to make it clearer "How do i make x.x see as text so that i can compare with x.x.x :) "

Here is an article/ post you may want to check. The first impression I had on your question is that you may be trying to do a version number comparison. Length and number of dot delimiters in your text could matter greatly.for now please check this,

Or else you may try the log as well:

=A1*10^(4-INT(LOG(A1)))

Or do a replace on trailing . dots and surely the second text becomes a decimal:

E.g. 1.3.4 will be 1.34 and 1.3.4.1.3 will be 1.3413

1.2.5.6 will be 125.6 and 1.2.4.6.1 will be 124.61

PS: not front of a machine. Will provide you with another code I have based on split by dot delimiter and compare.

Edit with a function: this will compare two version numbers with any number of dot points, treating it as a string/text. However in the case of 1.3.1 and 1.21.1 this takes 1.21.1 as the highest number.
