In the C Programming Language, the fabs function returns the absolute value of a floating-point number.

July 23, 2025 - fabs() function of math.h header file in C programming is used to get the absolute value of a floating point number.

#include <iostream> #include <cmath> int main() { std::cout << "abs(+3.0) = " << std::abs(+3.0) << '\n' << "abs(-3.0) = " << std::abs(-3.0) << '\n'; // special values std::cout << "abs(-0.0) = " << std::abs(-0.0) << '\n' << "abs(-Inf) = " << std::abs(-INFINITY) << '\n'; }

December 16, 2005 - #include <math.h> doublefabs( double x ); float fabsf( float x ); long double fabsl( long double x ); The fabs() function returns the absolute value of its floating-point argument x; if x is greater than or equal to 0, the return value is equal to x.

double abs (double x); float abs (float x);long double abs (long double x); double abs (T x); // additional overloads for integral types ... Returns the absolute value of x: |x|. These convenience abs overloads are exclusive of C++. In C, abs is only declared in <stdlib.h> (and operates on ...

Preliminary: | MT-Safe | AS-Safe | AC-Safe | See POSIX Safety Concepts. This function returns the absolute value of the floating-point number number.

December 12, 2024 - Define a floating-point variable with a negative value. Use fabs() to compute the absolute value.

Computes the absolute value of a floating point value arg.

If you ever end up comparing two floating-point numbers for equality, with f1 == f2, be suspicious. For example, try 0.1 + 0.2 == 0.3 to be disappointed. Consider using an “error tolerance” in comparisons, like abs(f1 - f2) < epsilon.

-- -- > min 42 12345678 == 42 -- > min "abc" "xyz" == "abc" min :: Prelude.Ord comparable => comparable -> comparable -> comparable min :: comparable -> comparable -> comparable min = comparable -> comparable -> comparable forall a. Ord a => a -> a -> a Prelude.min -- | Compare any two comparable values. Comparable values include @String@, -- @Char@, @Int@, @Float@, or a list or tuple containing comparable values.

If successful, returns the absolute value of arg (|arg|). The value returned is exact and does not depend on any rounding modes. This function is not subject to any of the error conditions specified in math_errhandling. If the implementation supports IEEE floating-point arithmetic (IEC 60559),

for 32-bit 2's complement type int, INT_MIN is -2147483648, but the would-be result 2147483648 is greater than INT_MAX, which is 2147483647. ... #include <limits.h> #include <stdio.h> #include <stdlib.h> int main(void) { printf("abs(+3) = %d\n", abs(+3)); printf("abs(-3) = %d\n", abs(-3)); // printf("%+d\n", abs(INT_MIN)); // undefined behavior on 2's complement systems }
