How do you find the number of digits after a decimal point?
- Take input as a string char str[10] = “245.98”;
- Convert string to int using to count the number of digits before the decimal point. int atoi(const char *string)
- Use logic n/10 inside the while to count the numbers.
- Numbers after decimal logic. Get the length of the string using strlen(n) inside the while (a[i]! =’. ‘).
How do I count the number of digits after a decimal in Excel?
Count and identify the decimal place of a number In a blank cell, saying the Cell B2, enter the formula of =IF(A2=INT(A2),0,LEN(MID(A2-INT(A2),FIND(“.”,A2,1),LEN(A2)-FIND(“.”,A2,1)))), and press the Enter key. Then it returns the decimal place in the Cell B2.
How do you find the number of digits in a decimal number?
If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. For example, the decimal 0.3 is the same as the fraction 310 . The second digit to the right of the decimal point indicates the number of hundredths.
How do I print 2 digits after a decimal?
we now see that the format specifier “\%. 2f” tells the printf method to print a floating point value (the double, x, in this case) with 2 decimal places.
How many digits are in a decimal after float?
The float data type has only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point.
How do I get 3 decimal places in Excel?
Round a number down by using the ROUNDDOWN function. It works just the same as ROUND, except that it always rounds a number down. For example, if you want to round down 3.14159 to three decimal places: =ROUNDDOWN(3.14159,3) which equals 3.141.
Can a double have decimals?
double is a 64 bit IEEE 754 double precision Floating Point Number (1 bit for the sign, 11 bits for the exponent, and 52* bits for the value), i.e. double has 15 decimal digits of precision.
How do you calculate digits?
Add the even number digits: 1+1+1+1+1=5. Add the two results together: 0 + 5 = 5. To calculate the check digit, take the remainder of (5 / 10), which is also known as (5 modulo 10), and if not 0, subtract from 10: i.e. (5 / 10) = 0 remainder 5; (10 – 5) = 5. Therefore, the check digit x value is 5.
What is base 16 called?
Hexadecimal is the name of the numbering system that is base 16. This system, therefore, has numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15.
How to get the number of digits after the decimal point?
As this string contains a front zero and decimal point, the digits after decimal point is (string length – 2). Subtract the float and its integer part, take the absolute value of result. Store result in a string stream.
How many decimal places are there in 6757?
That’s a bit tricky. IEEE floats can’t represent most decimal fractions exactly. The number 6757.658 is represented as a binary decimal: 0x1a65a872b020c5×2 -40, which is exactly 6757.6580000000003565219230949878692626953125 (I think). I.e., your number actually has 40 decimal places.
How do you find the remainder of the last digit?
If you want only one last digit, use x\%10, If you want last 2 digits, use x\%100 and so on. The modulus operator gives the remainder. Hope this helps.

How do I get the 1st digit of a number?
Let me explain the logic: Say the number is 72.1454 which you mentioned. Now if you want 1st digit after decimal, then multiply by 10, and for 2nd digit multiply by 100 and so on…For 1st digit we get 721.454 after multiplication. Now take mod of this number by 10 and store the result in any int data type variable.
