convert ViChar to double

[Mike McM.]

I am using a hp34970a driver. I am making a voltage measurement. The reading comes back as a ViChar data type. How do I convert this to a double so I can do math with it?

Hi Mike:

The ViChar data type is just like a regular char datatype.  VISA just puts a wrapper around it so it can be ported to different operating systems.  You can type cast this to a double just as you would for any char datatype.

ViChar mychar;
double mydouble;
mydouble = (double) mychar;
