[S,ERRMSG] = SPRINTF(FORMAT,A,) formats the data in the real, part of matrix A (and in any additional matrix arguments), under, control of the specified FORMAT string, and returns it in the, MATLAB string variable S. ERRMSG is an optional output argument, that returns an error message string if an error occurred or an, empty matrix if an error did not occur. When using the % signs to print out the data stored in variables, we People have difficulty understanding why a value that shows up as 0.1 does not compare as equal to 0.1: the limits of format long g have real effects. then prod(X,1) is [0 4 10] and prod(X,2) is [ 0. In short, this will round up for a positive value:Likewise, it will also round up for a negative value: For instance, in order to round to 3 decimal places, you just have to set the variable decimal to 3, and to round to 4 decimal places, run the code above for decimal=4. A = 3.1416 (Use a precision operator to specify the number of digits after the decimal point.) 10/3. Like "triptester" says, the secret is to use the right size dies. In the above 2 examples, we saw that all the values were rounded off to the nearest integers. MATLAB provides various commands for It is very annoying to have miscellaneous printouts from this is not even close to being an "absurdly huge number". "long g" format comes closest but is 1 digit short of uniquely identifying the stored binary. variable rather than writing it to a file. In MATLAB we use round function for the purpose of rounding off the numeric values. Here it prints the value of the variable num.
