Si se llama a std::abs con un argumento integral sin signo que integral promotion no puede convertir a int, el programa tiene un formato incorrecto. La sobrecarga (6) de std::abs para std::intmax_t se proporciona en si y solo si std::intmax_t es un extended integer type. (since C++11) Parameters.
std::abs(int), std::labs, std::llabs, std::imaxabs Is the std::abs() function well defined for ALL arithmetic types in C++11 and will return |x| with no problem of approximation? A weird thing is that with g++4.7, std::abs(char), std::abs(short in.If std::abs is called with an unsigned integral argument that cannot be converted to int by integral promotion, the program is ill-formed. Overload (6) of std::abs for std::intmax_t is provided in if and only if std::intmax_t is an extended integer type. (since C++11) Parameters. In C++, std::abs is overloaded for both signed integer and floating point types.std::fabs only deals with floating point types (pre C++11). Note that the std:: is important; the C function ::abs that is commonly available for legacy reasons will only handle int!. The problem with. float f2= fabs(-9); is not that there is no conversion from int (the type of -9) to .Return value. ใจใฉใผใ็บ็ใใชใๅ ดๅใฏใ z ใฎ็ตถๅฏพๅค (ใใซใ ใใขใธใฅใฉในใใพใใฏใใฐใใใฅใผใใจใๅผใฐใใพใ) ใ่ฟใใพใใ ใจใฉใผใจ็นๆฎใชใฑใผในใฏใ้ขๆฐใ std::hypot(std::real(z), std::imag(z)) ใจใใฆๅฎ่ฃ

Its boils down to this: math.h is from C and was created over 10 years ago. In math.h, due to its primitive nature, the abs() function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs().When C++ was created it took math.h and made it cmath.cmath is essentially math.h but improved for C++. I now have a slightly better answer: std::abs was only introduced in C++17. Prior to that, you had to use std::fabs to get a floating-point absolute value, and your same program would have complained that abs did not exist instead (possibly highlighting better that you were missing the correct #include).
