writef

Part of StandardLibraryCategory

Description

Since DMD 0.95, writef is available as a replacement for printf. (Access Violations can become a thing of the past.)

Example

import std.stdio;

void main()
{
    /* Integers */
    
    int i=123;

    writef(i, \n);         /* prints "123" */

    writef("%s", i, \n);   /* prints "123" */
    writef(\n);
    
    writef("Leading zeros\n");
    
    /* prints "123" (would have a leading zero or zeros if necessary) */
    writef("%02s", i, \n); 

    /* prints "123" (would have a leading zero or zeros if necessary) */

    writef("%03s", i, \n); 

    /* prints "0123" (leading zero) */
    writef("%04s", i, \n); 

    /* prints "00123" (leading zeros) */
    writef("%05s", i, \n); 


    /* Reals */

    real x = 1.0;
    writef(x, \n);
    writef("%f", x, \n);

    /* from digitalmars.D.bugs:894 */
    printf( "%Lf\n", x ); 



    x = 2.345;
    writef(x, \n);
    writef("%f", x, \n);

    /* from digitalmars.D.bugs:894 */

    printf( "%Lf\n", x ); 
}
