DA.Numeric¶
Functions¶
- mul
: NumericScale n3 => Numeric n1 -> Numeric n2 -> Numeric n3
Multiply two numerics. Both inputs and the output may have different scales, unlike
(*)which forces all numeric scales to be the same. Raises an error on overflow, rounds to chosen scale otherwise.
- div
: NumericScale n3 => Numeric n1 -> Numeric n2 -> Numeric n3
Divide two numerics. Both inputs and the output may have different scales, unlike
(/)which forces all numeric scales to be the same. Raises an error on overflow, rounds to chosen scale otherwise.
- cast
: NumericScale n2 => Numeric n1 -> Numeric n2
Cast a Numeric. Raises an error on overflow or loss of precision.
- castAndRound
: NumericScale n2 => Numeric n1 -> Numeric n2
Cast a Numeric. Raises an error on overflow, rounds to chosen scale otherwise.
- shift
: NumericScale n2 => Numeric n1 -> Numeric n2
Move the decimal point left or right by multiplying the numeric value by 10^(n1 - n2). Does not overflow or underflow.
- pi
: NumericScale n => Numeric n
The number pi.
