应为： from math import sqrt
from math import sqrt from cmath import sqrt from numpy import sqrt The weird thing is, when I do this, I still get the error: === nick at mws2[phylocom]|27> a = ["12", "15", "16", "38.2"] nick at mws2[phylocom]|28> from LR_run_functions_v2 import make_half_square_arr...
To access the function, you must #include the cmath header file. To calculate the square root of z and assign the floating point result to a double variable named I, write: double x = sqrt(z); where does not have to be defined if it...

The similar code in math.h also reference __builtin_xxx too. @xiaoxiang781216and@masayuki2009since you have more experience with C++ on NuttX, could you please take a look? My concern is that the code added in cmath is almost same as math.h, could w avoid the duplication?
I don't think moving things to std::__math::log is not a real solution; every C library vendor has to agree. Member ChuanqiXu9 commented Apr 28, 2024 I am wondering if we can fix it by: // cmath // #include <math.h> namespace std { double log(double); } // cmath.cc...
