Mathematics. h
Mathematical function library, the concrete realization of some mathematical calculation formulas is put in math.h, specifically: 1 trigonometric function double sin (double); Double cos (double); Shuangtan (double); 2 inverse trigonometric function doubleasin (double); The result is between [-PI/2, PI/2] double acos (double); The result is between [0, PI] double atan (double); Arctangent (principal value), the result is between [-pi/2, pi/2] double atan2 (double, double); Arctangent (integer value), the result is between [-PI/2, PI/2] 3 hyperbolic trigonometric function double sinh (double); Double cosh (double); Double tanh (double); 4 exponential sum logarithm double exp (double); double sqrt(double)； Double; Logarithmic doublelog10 (double) based on e; Double pow(double x, double y)// Calculate the power of y based on x, and round up Double Ceil (double); Take the whole double floor (double); Take the absolute value of the integer 6, double fabs (double); Double Cabs (struct complex znum)//Find the absolute value of the standardized floating-point number double frexp (double f, int *p) of complex number 7; Standardized floating-point number, f = x * 2^p, it is known that f finds x, p (x is between [0.5, 1]) double ldexp (double x, int p); Contrary to frexp, it is known that x and p find the integer f 8 and the remainder double modf (double, double *); Pass the pointer back to the integer part of the parameter and return the decimal part of double fmod (double, double); Returns the remainder of the division of two parameters: 9 Other double hypot(double x, Double Y); //Given the length of two right-angled sides of a right-angled triangle, find the hypotenuse length double ldexp (double x, int exposure); //Calculate x * (exponential power of 2) Double Poly (double x, int degree, double coeffs [])//Calculate polynomial nt matherr(struct exception *e)// Mathematical error calculation handler Source: C&: C++ Code Capsule.
