To leave a variable uninitialized, use the construction:
int x = void;
Note that nobody is going to write this by accident. And it's easy to grep for.
To find the source of a NaN, it helps to know that every operation that has a NaN as an operand produces a NaN as a result. So if you see a NaN in the output, you can work backwards to where it originated.
- jcranmer 6mo ago> every operation that has a NaN as an operand produces a NaN as a result. That's not true. The minimum/maximum functions (fmin and fminimum_num variants, but not the fminimum one) treat NaN inputs as not-present, so return the non-NaN value if there is one. Similarly, hypot also treats NaN inputs as not-present. pow and compoundn will ignore NaN exponents if the base is 1.
- WalterBright 6mo agoYes, there are some functions where if one operand has no effect on the result, a NaN value will also have no effect.
- ncurses1010 6mo agoWhat do you think of kotlins approach where it has a 'todo' function that can always coerce to a type, but instead of populating the variable with a default value that's valid, it just throws
