15 // Tests TInt64 |
|
16 // Overview: |
|
17 // Test 64-bit integer functionality. |
|
18 // API Information: |
|
19 // TInt64. |
|
20 // Details: |
|
21 // - Construct TInt64 with specified range of integer, real, high |
|
22 // and low values and check constructor, copy constructor are as expected. |
|
23 // - Test all the operators for range of values and check it is as expected. |
|
24 // - Check the logical shift of specified number of bits is as expected. |
|
25 // - Check multiplication of 64 bit integer by the specified 64 bit integer |
|
26 // using MulTop, fast multiplication of 64 bit integer by 10. |
|
27 // - Verify the 64 bit integer divide and mod results are as expected. |
|
28 // Platforms/Drives/Compatibility: |
|
29 // All. |
