Phix has both 32 and 64 bit implementations. Integers are signed and limited to 31 (or 63) bits, ie
-1,073,741,824 to +1,073,741,823 (-#40000000 to #3FFFFFFF) on 32 bit, whereas on
Line 1,705 ⟶ 1,706:
Integer overflow is handled by automatic promotion to atom (an IEEE float, 64/80 bit for the 32/64 bit implementations respectively),
which triggers a run-time type check if stored in a variable declared as integer, eg:
<!--<lang Phix>
<span style="color: #004080;">integer</span> <span style="color: #000000;">i</span> <span style="color: #0000FF;">=</span> <span style="color: #000000;">1000000000</span> <span style="color: #0000FF;">+</span> <span style="color: #000000;">1000000000</span>
