In order to supply predictable ranges, we require an Integral[T] which provides us with discrete operations on the (otherwise fractional) T. See Numeric.DoubleAsIfIntegral for an example.
Test two objects for inequality.
true if !(this == that), false otherwise.
Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.
a hash value consistent with ==
Returns true if this is less than that
Returns true if this is less than or equal to that.
Test two objects for equality. The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
true if the receiver object is equivalent to the argument; false otherwise.
Returns true if this is greater than that.
Returns true if this is greater than or equal to that.
Returns the absolute value of this.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.
the receiver object.
ClassCastException if the receiver object is not an instance of the erasure of type T0.
Result of comparing this with operand that.
Implement this method to determine how instances of A will be sorted.
Returns x where:
x < 0 when this < that
x == 0 when this == that
x > 0 when this > that
Result of comparing this with operand that.
Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).
Returns the runtime class representation of the object.
a class object corresponding to the runtime type of the receiver.
Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.
true if the receiver object is an instance of erasure of type T0; false otherwise.
Returns true iff this has a zero fractional part, and is within the range of scala.Byte MinValue and MaxValue; otherwise returns false.
Returns true iff this has a zero fractional part, and is within the range of scala.Char MinValue and MaxValue; otherwise returns false.
Returns true iff this has a zero fractional part, and is within the range of scala.Int MinValue and MaxValue; otherwise returns false.
Returns true iff this has a zero fractional part, and is within the range of scala.Short MinValue and MaxValue; otherwise returns false.
true if this number has no decimal component, false otherwise.
Returns this if this > that or that otherwise.
Returns this if this < that or that otherwise.
Returns the signum of this.
Returns the value of this as a scala.Byte. This may involve rounding or truncation.
Returns the value of this as a scala.Char. This may involve rounding or truncation.
Converts an angle measured in radians to an approximately equivalent angle measured in degrees.
the measurement of the angle x in degrees.
Returns the value of this as a scala.Double. This may involve rounding or truncation.
Returns the value of this as a scala.Float. This may involve rounding or truncation.
Returns the value of this as an scala.Int. This may involve rounding or truncation.
Returns the value of this as a scala.Long. This may involve rounding or truncation.
Converts an angle measured in degrees to an approximately equivalent angle measured in radians.
the measurement of the angle x in radians.
Returns the value of this as a scala.Short. This may involve rounding or truncation.
Returns a string representation of the object.
The default representation is platform dependent.
a string representation of the object.
Should only be called after all known non-primitive types have been excluded. This method won't dispatch anywhere else after checking against the primitives to avoid infinite recursion between equals and this on unknown "Number" variants.
Additionally, this should only be called if the numeric type is happy to be converted to Long, Float, and Double. If for instance a BigInt much larger than the Long range is sent here, it will claim equality with whatever Long is left in its lower 64 bits. Or a BigDecimal with more precision than Double can hold: same thing. There's no way given the interface available here to prevent this error.
