sqrt() - Mathematical Function
How is Mathematical Function "sqrt()" used in C++?
How to find the Square root of a number?
Explanation
sqrt() is a Mathematical Function that returns the square root of the given "num" value.
float sqrt( float num);
double sqrt( double num);
long double sqrt( long double num);
Result :
Square root of of 4:: 2.000000
In the above example sqrt() is used to find square root of "4".
Syntax to find the Square root:
float sqrt( float num);
double sqrt( double num);
long double sqrt( long double num);
Example :
| #include <stdio.h> #include <math.h> int main () { float r; r= sqrt(4); printf ("Square root of of 4:: %f\n", r ); return 0; } |
Result :
Square root of of 4:: 2.000000
In the above example sqrt() is used to find square root of "4".
