5 will be sufficient.
3.25 million is written in numbers as 3,250,000. This is done by placing the numeral 3 followed by a decimal point and the digits 25, then adding six zeros to represent the millions.
We have ten fingers (including thumbs) and early counting is based on one-to-one mapping onto these digits. So one reason is simple familiarity. The other advantage of counting in decimals is that fewer digits are required: 4 decimal digits takes you to over a thousand, you would need 10 binary digits to go over 1024. It gets worse with larger numbers: 7 decimal digits to go over a million but 20 binary digit. I have phones with 11 digit numbers (without the international country code). In binary, that would be a 33-digit number. No thanks!
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
-- The decimal system (base-10) uses 10 digits to write all numbers. -- The binary system (base-2) uses 2 digits to write all numbers.
To write out a certain number of millions, move the decimal point six positions to the right. If there are not enough digits, fill out with zeros.
1 million < 165 so 6 digits would be enough.
Seven will be more than enough.
The answer depends on the degree of precision. If only integers are to be represented, then 6 digits would be enough because 165 = 1,048,576 is bigger than a million.
Oh, that's a wonderful question! To represent decimal numbers up to 1 million in hexadecimal, you would need about 4 hex digits. Hexadecimal is base 16, so each digit can represent 16 different values (0-9 and A-F), making it an efficient way to represent large numbers in a compact form. Just imagine those beautiful hex digits coming together like little puzzle pieces to create the number 1 million - what a happy little number!
Eliminate the decimal point, and make sure that there are six more digits after the "2". Fill out missing digits with 0.

It displays numbers with more digits after the decimal point.

If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
All of them. We normally count in decimal numbers and therefore all digits in decimal numbers must be less than ten.
The two digits after the decimal point.
