Check if a
is an Even number after a truncation.
fractionDigits
: number of decimal digits
Implementation
bool isEvenDouble(double a, int fractionDigits) {
var aT = truncate(a, fractionDigits);
var aTString = aT.toString();
var last = int.parse(aTString[aTString.length - 1]);
return last % 2 == 0;
}
