Extended data:
Absolute value function in c language
Different types of data use different types of absolute value functions:
1, integer:
int abs(int i)? //Returns the absolute value of the integer parameter I 12.
2. plural:
Double cab (complicated structure znum)? //Returns the absolute value of the complex number znum? 1
3, double precision floating-point type:
Double fab (double x)? //Returns the absolute value of the double-precision parameter X 1
4. Long integer:
Dragon labs (dragon n)? //Returns the absolute value of long integer parameter n.
