Bloody hell Bernie! Are trying to make helping you difficult!?
Let's see if I can get a straight and complete answer this time...
You are getting -2147483648 when you use "sprintf".
You are also getting -2147483648 when you use "printf".
In other words, the program below ...
puts(1, sprintf("%d", 3217040639)) puts(1, " : from sprintf\n") printf(1, "%d : from printf\n", 3217040639)
Shows the following on your screen...
-2147483648 : from sprintf -2147483648 : from printf
Can you run the following two programs for me ...
-- Program 1 atom a a = 3217040635 for i = 1 to 10 do puts(1, sprintf("%d: %d", {i, a})) puts(1, "\n") a += 1 end for
-- Program 2 atom a a = -2147483645 for i = 1 to 10 do puts(1, sprintf("%d: %d", {i, a})) puts(1, "\n") a += 1 end for
And show us the results you are getting.
By the way, 0x80000000 when stored in a C long integer represents a sequence that has not been allocated any memory in Euphoria. It does NOT represent the lowest Euphoria integer value.
The value 0x800000000 when stored in Euphoria is actually stored as a C double and not a C int.
You are getting -2147483648 when you use "sprintf". YES. You are also getting -2147483648 when you use "printf". YES. -- ============================================================================= This is exact screen printed out using EXW on WIN98 Program 1 output 1: -2147483648 2: -2147483648 3: -2147483648 4: -2147483648 5: -2147483648 6: -2147483648 7: -2147483648 8: -2147483648 9: -2147483648 10: -2147483648 Program 2 output 1: -2147483645 2: -2147483644 3: -2147483643 4: -2147483642 5: -2147483641 6: -2147483640 7: -2147483639 8: -2147483638 9: -2147483637 10: -2147483636 This is exact screen printed out using EXWC on WIN98 Program 1 output 1: -2147483648 2: -2147483648 3: -2147483648 4: -2147483648 5: -2147483648 6: -2147483648 7: -2147483648 8: -2147483648 9: -2147483648 10: -2147483648 Program 2 output 1: -2147483645 2: -2147483644 3: -2147483643 4: -2147483642 5: -2147483641 6: -2147483640 7: -2147483639 8: -2147483638 9: -2147483637 10: -2147483636 This is exact screen printed out using EX on WIN98 Program 1 output 1: -2147483648 2: -2147483648 3: -2147483648 4: -2147483648 5: -2147483648 6: -2147483648 7: -2147483648 8: -2147483648 9: -2147483648 10: -2147483648 Program 2 output 1: -2147483645 2: -2147483644 3: -2147483643 4: -2147483642 5: -2147483641 6: -2147483640 7: -2147483639 8: -2147483638 9: -2147483637 10: -2147483636 -- =============================================================================
