借助cmath.sqrt()方法,通过将其传递给cmath.sqrt()方法。 用法:cmath.sqrt(value) 返回:Return the square root of any value. 范例1: 在这个例子中,我们可以通过使用cmath.sqrt()方法,我们可以通过将平方根值传递给它来获得平方根的值。 # importing cmath libraryimportcmath# using cmath.sqrt() method...
sinh(x) Returns the hyperbolic sine of x sqrt(x) Returns the square root of x tan(x) Returns the tangent of x (x is in radians) tanh(x) Returns the hyperbolic tangent of x tgamma(x) Returns the value of the gamma function at x trunc(x) Returns the integer part of xLearn...
hypot(x, y) Returns sqrt(x2 +y2) without intermediate overflow or underflow ilogb(x) Returns the integer part of the floating-point base logarithm of x ldexp(x, y) Returns x*2y lgamma(x) Returns the logarithm of the absolute value of the gamma function at x llrint(x) Rounds x to ...
Example: C sqrt() Function #include <math.h> #include <stdio.h> int main() { double number, squareRoot; printf("Enter a number: "); scanf("%lf", &number); // computing the square root squareRoot = sqrt(number); printf("Square root of %.2lf = %.2lf", number, squareRoot);...
在Unix/Linux环境中，man命令可以查阅在线的手册页，例如 man 3 sqrt 可查阅math.h中sqrt函数的说明。
然而, Borland 用来确定程序是否使用了浮点运算的探测法并不充分, 程序员有时必需调用一个空浮点库函数 (例如sqrt(), 或任何一个函数都可以) 以强制装载浮点支持。参见 comp.os.msdos.programmer FAQ 以获取更多信息。 可变参数 15.1 为什么调用 printf() 前, 必须要用 #include <stdio.h>? 为了把 printf(...
#include <math.h> int main() { double x = 2.0; double y = 3.0; // 基本运算 printf("sqrt(%.1f) = %.2f\n", x, sqrt(x)); printf("pow(%.1f, %.1f) = %.2f\n", x, y, pow(x, y)); printf("exp(%.1f) = %.2f\n", x, exp(x)); printf("log(%.1f) = %.2f\...
sqrt(x) This function returns the square root of x. 3 cbrt(x) This function returns the cubic root of x. 4 hypot(x,y) This function returns the hypotenuse of a right-angled triangle whose legs are x and y. Raising a Base to a Given Exponent In the following example we are going ...
Following is the C library program that illustrates the usage of sqrt() function.Open Compiler #include <stdio.h> #include <math.h> int main () { printf("Square root of %lf is %lf\n", 4.0, sqrt(4.0) ); printf("Square root of %lf is %lf\n", 5.0, sqrt(5.0) ); return(0)...
