# MathRand
|
|||
|
|
|
|||
|
|
Returns a pseudorandom integer within the range of 0 to 32767.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
int MathRand();
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Return Value
|
|||
|
|
|
|||
|
|
Integer value within the range of 0 to 32767.
|
|||
|
|
|
|||
|
|
Note
|
|||
|
|
|
|||
|
|
Before the first call of the function, it's necessary to call [MathSrand](/en/docs/math/mathsrand) to set the generator of pseudorandom numbers to the initial state.
|
|||
|
|
|
|||
|
|
Note
|
|||
|
|
|
|||
|
|
Instead of MathRand() you can use rand().
|
|||
|
|
|
|||
|
|
Example:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
//+------------------------------------------------------------------+
|
|||
|
|
//| Script program start function |
|
|||
|
|
//+------------------------------------------------------------------+
|
|||
|
|
void OnStart()
|
|||
|
|
{
|
|||
|
|
//--- set a new initial state to generate a series of pseudo-random integers at each launch
|
|||
|
|
MathSrand(GetTickCount());
|
|||
|
|
//--- in a loop, display 10 generated pseudo-random integers in the journal
|
|||
|
|
for(int i=0; i<10; i++)
|
|||
|
|
{
|
|||
|
|
int rand_value=MathRand();
|
|||
|
|
PrintFormat("Pseudorandom integer №%d: %u",i+1,rand_value);
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
```
