If command

[sakkoyun]

I would like to know usage of the If command. An example is,
************************************************** **************

  varmult  = (mult > 0) ? (0) : (1);

  mult     = MIN(MAX(ABS(mult), 1), MAXMULT);

  if(mult == 1) varmult = 0;

  if(varmult) {

    varmult = MAX(1, (mult * 4) / 5);

    sigmult = mult/4./SIG2FW;

  }

************************************************** ***************

what is the mean of the if(varmult) ?
best wishes

if(varmult) is a shorter way to write if(varmult != 0). In C and C++, any variable is "true" if it's non-zero, and "false" if it's zero.
