dynamic extBETWEEN(
  1. dynamic v1,
  2. dynamic v2,
  3. dynamic v3
)

BETWEEN(value, lo, hi): whether a value is within the lo, hi range

Implementation

dynamic extBETWEEN(dynamic v1, dynamic v2, dynamic v3) {
  final val = varToDouble(v1);
  final lo = varToDouble(v2);
  final hi = varToDouble(v3);
  return val >= lo && val <= hi;
}
