# MathMin
|
|||
|
|
|
|||
|
|
The function returns the minimal value of two values.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
double MathMin(
|
|||
|
|
double value1, // first value
|
|||
|
|
double value2 // second value
|
|||
|
|
);
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Parameters
|
|||
|
|
|
|||
|
|
value1
|
|||
|
|
|
|||
|
|
[in] First numeric value.
|
|||
|
|
|
|||
|
|
value2
|
|||
|
|
|
|||
|
|
[in] Second numeric value.
|
|||
|
|
|
|||
|
|
Return Value
|
|||
|
|
|
|||
|
|
The smallest of the two values.
|
|||
|
|
|
|||
|
|
Note
|
|||
|
|
|
|||
|
|
Instead of MathMin() you can use fmin(). Functions fmax(), [fmin()](/en/docs/math/mathmin), [MathMax](/en/docs/math/mathmax)(), [MathMin()](/en/docs/math/mathmin) can work with integer types without typecasting them to the type of double.
|
|||
|
|
|
|||
|
|
If parameters of different types are passed into a function, the parameter of the smaller type is automatically [cast](/en/docs/basis/types/casting) to the larger type. The type of the return value corresponds to the larger type.
|
|||
|
|
|
|||
|
|
If data of the same type are passed, no casting is performed.
|
|||
|
|
|
|||
|
|
Example:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
//--- input parameters
|
|||
|
|
input uint InpBars = 100000; // Desired number of bars
|
|||
|

|
|||
|
|
{
|
|||
|
|
//--- get the number of available bars on the server
|
|||
|
|
uint bars_total = Bars(Symbol(),Period());
|
|||
|
|
if(bars_total==0)
|
|||
|
|
{
|
|||
|
|
PrintFormat("Data for timeseries %s %s not yet generated in the terminal. Please try again later.",Symbol(),StringSubstr(EnumToString(Period()),7));
|
|||
|
|
return;
|
|||
|
|
}
|
|||
|
|
//--- get the minimum number of bars from two values - from those available on the server and from the requested number in the settings
|
|||
|
|
int bars = (int)MathMin(bars_total,InpBars);
|
|||
|
|
//--- if more bars are requested than are available on the server, report this in the journal
|
|||
|
|
if(bars_total<InpBars)
|
|||
|
|
PrintFormat("Number of bars on the server (%u) is less than requested (%u)",bars_total,InpBars);
|
|||
|
|
//--- display the number of bars available for work in the journal
|
|||
|
|
Print("Bars available for work: ",bars);
|
|||
|
|
}
