convertValue method
Returns value, converted to the units represented by newNumerators and
newDenominators.
Throws a SassScriptException if this number's units aren't compatible
with newNumerators and newDenominators or if this number is unitless.
If this came from a function argument, name is the argument name
(without the $). It's used for error reporting.
Implementation
double convertValue(
List<String> newNumerators,
List<String> newDenominators, [
String? name,
]) =>
_coerceOrConvertValue(
newNumerators,
newDenominators,
coerceUnitless: false,
name: name,
);
