It is called a 28-digit number!
A 1000-digit number is called a "millidigit" number. The prefix "milli-" denotes one thousandth, so a millidigit number is a number consisting of 1000 digits. In the realm of mathematics, such large numbers are often encountered in fields like cryptography, number theory, and computer science.
Just that - a 26-digit number. There is no special name for that.
Rounding to the first digit is simply called rounding. This will make the number equal to the same as what the number truly is.
A number that has more than one digit is called a "multi-digit number." In mathematics, a digit is a single symbol used to represent numbers (0-9). Therefore, a number with two or more of these symbols is considered a multi-digit number. These numbers can be broken down into individual place values, such as units, tens, hundreds, and so on.
32 is the smallest two-digit number that can be multiplied by itself to give a four-digit number. (32x32)=1024
yes 16 digit number
9984 is the largest 4-digit multiple of 32
32 x 32 = 1024
32
No.
Not in a way that would be generally understood. However, it is possible. An 8-digit number in base 10 can be represented by a 5-digit number in base 32. For example, extending the scheme for labeling digits for base 32, VVVVV32 = 3355443110 Similarly, the 8-digit number 33333333 in base 4 is the 5-digit number 65535 in base 10
It is called a 28-digit number!
A 12-digit number is called a trillion. In the International System of Numeration, each group of three digits is named based on powers of a thousand. Therefore, a 12-digit number would represent a quantity in the trillions.
I suggest you just call it that - a "35-digit number".
The value of a digit in a number is called its place value.
We generally refer to them by the number of digits. Two-digit number, three-digit number, etc.
