lz_add
The sum of two numbers.
long lz_add( CLZNumber* leftOperand, CLZNumber* rightOperand, CLZNumber* targetNumber = nullptr );The sum is exact unless it has more places than the working precision, when it is rounded in the target's own rounding mode, half-even unless the target is set otherwise. A right operand in another base is brought into the left one's base first, on a copy, so 0x15 + 0b1010 answers in hexadecimal.
Examples
| Call | Answer |
|---|---|
lz_add( 0.1, 0.2 ) | 0.3 |
lz_add( 0x15, 0b1010 ) | 1F base 16 |
lz_add( 99999999999999999999, 1 ) | 100000000000000000000 |
Each answer is what Addaptic printed for the call, at 36 places unless a setting is shown.
Returns
kNoError (0) when the answer is written. Otherwise an error code, with the answer flagged infinite or not-a-number; see Errors and flags.
