How do printf's format specifiers e and f differ in their treatment of floating-point numbers?

%f prints the corresponding number as a decimal floating point number (e.g. 321.65), %e prints the number in scientific notation (e.g. 3.2165e+2), %g prints the number in the shortest of these two representations (using the same number, the decimal floating point is shorter and hence 321.65 would be printed.

What is the difference between %g and %f?

%f represents the data in normal decimal form, upto six decimal places, although you can control, that upto how many decimal places did you want your output. %g represents the decimal format of the answer, depending upon whose length is smaller, comparing between %e and %f.

What is the difference between percentage E and percentage G?

They are both examples of floating point input/output. %g and %G are simplifiers of the scientific notation floats %e and %E. %g will take a number that could be represented as %f (a simple float or double) or %e (scientific notation) and return it as the shorter of the two.

What is the argument specifier for a floating point number?

Type conversion specifier. ... Floating-point types such as float , double , and long double , are specified by using a , A , e , E , f , F , g , and G . By default, unless they're modified by a size prefix, integer arguments are coerced to int type, and floating-point arguments are coerced to double .

What are format specifiers?

Format specifiers can be defined as the operators which are used in association with printf() function for printing the data that is referred by any object or any variable. ... Format specifiers start with a percentage % operator and followed by a special character for identifying the type of data.

Which format specifier is used for reading an integer type of value in scanf function?

"The format specifier required for the function scanf() is %c which is needed to read the character. ... Each data type category has its own format specifier %d for decimal(int), %f for floating type (double and float), %s for string, etc."

What is the difference between %e and g *?

%e is used to to represent a number with scientific notations. %g is used when we want the compiler to decide when to use “ %e or %f(decimal notation)” notations. If the size of exponent is less than -4 (<-4) , it uses %e.

What is the difference between %F and LF?

%f is the format string for a float, the single precision floating-point type. %lf is the format string for a double, the double precision floating-point type.

What is G format?

The general ("G") format specifier converts a number to the more compact of either fixed-point or scientific notation, depending on the type of the number and whether a precision specifier is present. The precision specifier defines the maximum number of significant digits that can appear in the result string.

What is the argument specifier for a floating point number in Python?

2f is a placeholder for floating point number. So %d is replaced by the first value of the tuple i.e 12 and %. 2f is replaced by second value i.e 150.87612 .

What are format specifiers in Java?

Java String Format Specifiers

decimal number, possibly in scientific notation depending on the precision and value. %h. any type. Hex String of value from hashCode() method. %n.

Which of the following format specifiers is used to provide exactly 4 digits after decimal point?

In C, there is a format specifier in C. To print 4 digits after dot, we can use 0.4f in printf().
