FixedPoint is a value class that provides fixed point arithmetic operations (using an implicit denominator) to unboxed Long values.
FixedPoint is a value class that provides fixed point arithmetic operations (using an implicit denominator) to unboxed Long values.
Working with FixedPoint values is similar to other fractional types, except that most operations require an implicit FixedScale instance (which provides the denominator).
For example:
// interpret FixedPoint(n) as n/1000
implicit val scale = FixedScale(1000)
// these three values are equivalent
val a = FixedPoint("12.345") // decimal repr
val b = FixedPoint(Rational(2469, 200)) // fraction repr
val c = new FixedPoint(12345L) // "raw" repr
