C: printf a float value

Question

I want to print a float value which has 2 integer digits and 6 decimal digits after the comma. If I just use printf(\"%f\", myFloat) I\'m getting a truncated va

Answer 1

You can do it like this:

printf("%.6f", myFloat);

6 represents the number of digits after the decimal separator.

Answer 2

printf("%9.6f", myFloat) specifies a format with 9 total characters: 2 digits before the dot, the dot itself, and six digits after the dot.

Answer 3

You need to use %2.6f instead of %f in your printf statement

Answer 4

printf("%.<number>f", myFloat) //where <number> - digit after comma

Answer 5

printf("%0k.yf" float_variable_name)

Here k is the total number of characters you want to get printed. k = x + 1 + y (+ 1 for the dot) and float_variable_name is the float variable that you want to get printed.

Suppose you want to print x digits before the decimal point and y digits after it. Now, if the number of digits before float_variable_name is less than x, then it will automatically prepend that many zeroes before it.

Answer 6

Use %.6f. This will print 6 decimals.
