divide by undefined is zero #674

Closed jvasileff closed 8 years ago

jvasileff commented 8 years ago 
print(-0.0 / (0.0/0.0));

prints -0.0 but should print NaN.

print NaN, or throw?

jvasileff commented 8 years ago

This claims NaN for ±0/±0.

chochos commented 8 years ago

jvasileff commented 8 years ago

This is already the way it works on the Java backend, and also the JavaScript backend for positive zero.
