21 maj 2024 · Rounding Floating Point Number To two Decimal Places in C and C++. Last Updated : 21 May, 2024. How to round off a floating point value to two places. For example, 5.567 should become 5.57 and 5.534 should become 5.53. First Method:- Using Float precision.
I have a list of float values and I want to print them with cout with 2 decimal places. For example: 10.900 should be printed as 10.90; 1.000 should be printed as 1.00; 122.345 should be printed as 122.34; How can I do this? (setprecision doesn't seem to help in this.)
To print float values in C, we use the printf() function along with the %f specifier. The %f specifier is used to print float values with default precision. The syntax for using the printf() function to print float values is as follows: printf("%f", floatVariable);
Example. float myFloatNum = 3.5; printf ("%f\n", myFloatNum); // Default will show 6 digits after the decimal point. printf ("%.1f\n", myFloatNum); // Only show 1 digit. printf ("%.2f\n", myFloatNum); // Only show 2 digits. printf ("%.4f", myFloatNum); // Only show 4 digits. Try it Yourself ».
In C programming, decimals or floating-point numbers can be represented using the float and double data types. This tutorial will provide an overview of these data types, how to use them, and how to perform basic arithmetic operations with them. Declaring and initializing float and double.
In this tutorial, we will learn how to format and print a float variable with 2 decimal places in the C programming language. We will write a function that takes a float variable as input and prints its value with 2 decimal places.
