Take absolute value symbols in C language

In C language, the absolute value symbol is abs() . It converts the number stored in the parameter to its absolute value, i.e., non-negative number.

How to use:

 <code class="c">#include <stdlib.h> int abs(int number);</stdlib.h></code>

abs() function takes an integer parameter number and returns its absolute value. If number is a positive number, it returns itself; if it is a negative number, it returns its opposite number.

Example:

 <code class="c">#include <stdio.h> int main() { int number = -10; printf("number = %d\n", number); printf("Absolute value of number = %d\n", abs(number)); return 0; }</stdio.h></code>

Output:

 <code>number = -10 Absolute value of number = 10</code>

Notes:

• abs() function can only be used for integers. If you want to take absolute values ​​for floating point numbers or other data types, you can use other library functions or write custom functions.
• abs() function returns an integer value. If you need floating point results, use the fabs() function.
