How to pass float type argument from the command line

[3Nex]

I want to be able to call my program as ./program 2.5 and then read that argument from my main function into a variable and have the variable's value to be 2.5.

All I get from the internets are either confusing examples or single character (instead of float) examples. Could you post a sample code for this plz?

int main(int argc,char *argv[] ) {
   if( argc > 1 ) {
     double x;
     x = atof(argv[1]);  // alternative strtod
   }


  return 0;
}
