Javascript parseFloat() change number [closed]

I have a strange problem with JavaScript .
I have text value in a textbox '25000000' when i am
using parsefloat(txt.value), the returned value is 25000 !??

Why is 25000000 changed to 25000 ?

Is it definitely all zeros? If there was an O hidden in there instead for instance, the parseFloat would stop at that point and return just what had been parsed so far. Other than that, there's not really enough information in your question to give you an answer.

Can you provide a minimal, complete and verifiable example that demonstrates the problem?

I think there is an alphabet somewhere in your numbers. Check the example below.There is an error in your code.

parseFloat(" 250000000 ") = 250000000

parseFloat("2018@geeksforgeeks") = 2018

parseFloat("geeksforgeeks@2018") = NaN

Thanks for all Responses.
The problem was for ',' in price.
Of course we replace ',' with '' ,but replace method
only change first one like "25,000,000,000"=>"25000,000,000".
I used str.split(',').join('') and problem solve and parsefloat returned correctly.
regards
