Bug 87077 – [Forms][Meter][Progress] Change function signature of parseToDoubleForNumberType

• Component: Forms
• Status: RESOLVED FIXED

This proposal is for 
* reducing number of lines in call sites for ease of maintenance, 
* be functional style (no side effect and increasing chance to use floating pointer register)

== Current Pattern 1 ==
double numberValue;
if (!parseToDoubleForNumberType(string, &numberValue))
  return defaultValue;
ASSERT(isfinite(numberValue));
return numberValue;

== New Pattern 1 ==
return parseToDoubleForNumberType(string, defaultValue)

== Current Pattern  2 ==
double max;
bool ok = parseToDoubleForNumberType(string, &max);
if (!ok || max <= 0)
  return 1;
return max;

== New Pattern 2 ==
return max(parseToDoubleForNumberType(string), 1);

== Current Pattern 3 ==
return !value.isEmpty() && !parseToDoubleForNumberType(value, 0);

== New Pattern 3 ==
return !value.isEmpty() && isfinite(parseToDubleForNumberType(value));

== Current Pattern 4 ==
double min = 0;
parseToDoubleForNumberType(string, &min);
return min;

== New Pattern 4 ==
return parseToDoubleForNumberType(string, 0);

Could you review changes?

This change helps introducing decimal arithmetic for allowing us to use const reference of Decimal object.

Thanks in advance.

It's worth giving a parameter name since the intention isn't clear for this case.

> +double parseToDoubleForNumberTypeWithDecimalPlaces(const String&, unsigned*, double);

Ditto.
