There is integer variable, voltage in millivolts.
signed int voltage_mv = 134; //134mV
I have 2-segment display and I want to display hundredths of volts.
How can I convert milivolts to hundredths volts in one operation? Without IF statement, without function?
134 => 13
135 => 14
How about simple rounding:
int millivoltToDisplay (int millivolts)
{
return (millivolts+5)/10;
}
(written as a function for clarity)
For the same of completeness, if the denominator is odd, then instead of doing:
return (millivolts+denominator/2)/denominator;
you can just have
return (2*millivolts+denominator)/(2*denominator);
and get the correct rounding.
