You have to add NumberStyles.AllowDecimalPoint too: Decimal.Parse(“2.09550901805872E-05″, NumberStyles.AllowExponent | NumberStyles.AllowDecimalPoint); MSDN is clear about that: Indicates that the numeric string can be in exponential notation. The AllowExponent flag allows the parsed string to contain an exponent that begins with the “E” or “e” character and that is followed by an optional positive or negative sign … Read more
You should be able use the String value in the Attribute and set the Parameter type to Decimal, it get’s converted automatically by the Test Framework as far as I can tell. [Theory] [InlineData(“37.60”)] public void MyDecimalTest(Decimal number) { Assert.Equal(number, 37.60M); } If this doesn’t work then you can manually convert it by passing in … Read more
function insertDecimal(num) { return (num / 100).toFixed(2); }
decimal stores 28 or 29 significant digits (96 bits). Basically the mantissa is in the range -/+ 79,228,162,514,264,337,593,543,950,335. That means up to about 7.9…. you can get 29 significant digits accurately – but above that you can’t. That’s why both the 8 and the 9 go wrong, but not the earlier values. You should only … Read more
The type of a literal without the m suffix is double – it’s as simple as that. You can’t initialize a float that way either: float x = 10.0; // Fail The type of the literal should be made clear from the literal itself, and the type of variable it’s assigned to should be assignable … Read more
You could use the modulo operation to check if there is a non-integer remainder: >>> from decimal import Decimal >>> Decimal(‘3.14’) % 1 == 0 False >>> Decimal(‘3’) % 1 == 0 True >>> Decimal(‘3.0’) % 1 == 0 True
It is not (no longer) recommended you create a subclass; the json.dump() and json.dumps() functions take a default function: def decimal_default(obj): if isinstance(obj, decimal.Decimal): return float(obj) raise TypeError json.dumps({‘x’: decimal.Decimal(‘5.5’)}, default=decimal_default) Demo: >>> def decimal_default(obj): … if isinstance(obj, decimal.Decimal): … return float(obj) … raise TypeError … >>> json.dumps({‘x’: decimal.Decimal(‘5.5’)}, default=decimal_default) ‘{“x”: 5.5}’ The code you … Read more
The decimal point might not be represented by the period character in your current culture. In general, when performing culture-invariant conversions, it’s best to specify CultureInfo.InvariantCulture as the IFormatProvider argument to the method: (decimal) Convert.ChangeType(a, typeof(decimal), CultureInfo.InvariantCulture);
Here, a!! is defined as (a!)!. 123!!!!!! is absolutely gigantic. I think you’d need more particles than there are in the universe if you were to write it down in ink. You can’t therefore compare the numbers directly. I conject that there is not a number class that can do this. What you can do, … Read more
