Why is there an implicit conversion from Float/Double to BigDecimal, but not from String?
- by soc
Although the situation of conversion from Doubles to BigDecimals has improved a bit compared to Java
scala> new java.math.BigDecimal(0.2)
res0: java.math.BigDecimal = 0.20000000000000001110223024625156...
scala> BigDecimal(0.2)
res1: scala.math.BigDecimal = 0.2
and things like
val numbers: List[BigDecimal] = List(1.2, 3.2, 0.7, 0.8, 1.1)
work really well, wouldn't it be reasonable to have an implicit conversion like
implicit def String2BigDecimal(s: String) = BigDecimal(s)
available by default which can convert Strings to BigDecimals like this?
val numbers: List[BigDecimal] = List("1.2", "3.2", "0.7", "0.8", "1.1")
Or am I missing something and Scala resolved all "problems" of Java with using the BigDecimal constructor with a floating point value instead of a String, and BigDecimal(String) is basically not needed anymore in Scala?
