![]() There are tricks here though, you may read about those under the Ref link. and you will see some of the last ones dropped off. This area of knowledge includes lengthy texts within 'Discrete mathematics'.Įxcel uses double precision floating point numbers, which have a limit somewhere near "16 digits" e.g. Thanks But I just want it to be numeric not string. You may probably find a load of literature on creation of numeric representation in computers. You can convert a number to a string with n decimal places using the SPRINTF command: > x 1.23 > sprintf ('0.6f', x) ans 1.230000 > x 1.23456789 > sprintf ('0.6f', x) ans 1.234568. Therefore the problem is present in the "floating point" -numbers that is used in Excel and most other computer software packages. 2f prints the value up to 2 decimal places i.e, basically rounding off the value of x. Inside computers 1/10, 1/100 and so on has the same problem it cannot be represented EXACTLY in the same manner (using base two, with zeroes and ones). print('.2f' x) using the format specifier '' to print value till 2 decimal places print('.3f' x) using the format specifier '' to print value till 2 decimal places print('.4f' x) Output: 4.57 4.567 4.5675 From the above code, we can see that. 0.3333333 is only APPROXIMATELY equal to 1/3. For instance, we can print ten digits after. The problem is similar to the fact that the result of one divided by three cannot be written out on paper with all decimals, i.e. We can control the number of decimal places by adding a point and a number between the percentage sign and the f. The place of the asterisk should match the place of the number specifying the fields in the input arguments.Your question has the true answer 'inside' the technology used to represent numbers in computers. To specify the field width and precision outside the format specifier, use an asterisk (*) in place of the field width or precision fields of the formatting operator. in fixed point, using only two decimals b) display every final result as a real. If the field width w is higher than p 1 n, then the whole part of the output is padded to the left with either space or zero additional characters, calculated as w-(p 1 n).įield Width and Precision, Outside the Format Specifier hey, how can I set my matlab program to round all the.If the field width w is not specified, then the default value is calculated as per p 1 n, n is the number of digits in the whole part of an input value.of digits in the fractional part, then the fractional part is shown with added zeroes to the right of p digits. The following code sets up a variable that formats money values: DecimalFormat format new DecimalFormat(0.00). If the precision p is higher than the no.If precision p is less than the number of a digit in the fractional part of the input, then only p digits are displayed after the decimal point, and the output value is rounded off.If precision is not specified, then the default value is set to six.Let's examine with an illustrated example: ![]() And field width
