How do I add Letter M when number reaches million

SORRY FOR BAD ENLISH

How do I add a M B T
At the end of a Large number so it doesn't display too many 000000s

len(yourtext)=9=m
len(yourtext)=12=b
len(yourtext)=16=t

Maybe something like:

score >= 1000000000000
-> displayText = int(score/1000000000000) & "T"
else score >= 1000000000
-> displayText = int(score/1000000000) & "B"
else score >= 1000000
-> displayText = int(score/1000000) & "M"
else
-> displayText = score

Thanks everyone appreciate it

Sorry for ressurecting this thread. I followed OddConfection instructions and managed to display the numbers how i wanted them as well except for the numbers between 1Million and 10 Million.
I would like to be able to display for example 1 million and 200 thousand as 1.2 M until it reaches 10 million, but i don´t seem to able to do that.
Would anyone be kind enough to teach me?
Thanks in advance.

I've added in something so values over 10M are treated the same as before, but values between 1M and 10M are rounded to 1 decimal place.

score >= 1000000000000
-> displayText = int(score/1000000000000) & "T"
else score >= 1000000000
-> displayText = int(score/1000000000) & "B"
else score >= 10000000
-> displayText = int(score/1000000) & "M"
else score >= 1000000
-> displayText = int(score/100000)/10 & "M"
else
-> displayText = score
