cimagf, cimag, cimagl

Defined in header <complex.h> 
float       cimagf( float complex z );
+		 (1) (since C99) 
double      cimag( double complex z );
+		 (2) (since C99) 
long double cimagl( long double complex z );
+		 (3) (since C99)
Defined in header <tgmath.h> 
#define cimag( z )
+		 (4) (since C99)
+1-3) Returns the imaginary part of z.
+4) Type-generic macro: if z has type long double complex, long double imaginary, or long double, cimagl is called. If z has type float complex, float imaginary, or float, cimagf is called. If z has type double complex, double imaginary, double, or any integer type, cimag is called.

Parameters

+ +
z - complex argument

Return value

The imaginary part of z.

+

This function is fully specified for all possible inputs and is not subject to any errors described in math_errhandling

+

Notes

For any complex variable z, z == creal(z) + I*cimag(z).

+

Example

#include <stdio.h>
+#include <complex.h>
+ 
+int main(void)
+{    
+    double complex z = 1.0 + 2.0*I;
+    printf("%f%+fi\n", creal(z), cimag(z));
+}

Output:

+
1.000000+2.000000i
