// - Construct TInt64 with specified range of integer, real, high

// and low values and check constructor, copy constructor are as expected.
|
|
sl@0
|
23 |
// - Test all the operators for range of values and check it is as expected.
|
|
sl@0
|
24 |
// - Check the logical shift of specified number of bits is as expected.
|
|
sl@0
|
25 |
// - Check multiplication of 64 bit integer by the specified 64 bit integer
|
|
sl@0
|
26 |
// using MulTop, fast multiplication of 64 bit integer by 10.
|
|
sl@0
|
27 |
// - Verify the 64 bit integer divide and mod results are as expected.
