MathFloor
MathFloor
The function returns integer numeric value closest from below.
double MathFloor(
double val // number
);Parameters
- val
[in] Numeric value.
Return Value
A numeric value representing the largest integer that is less than or equal to val.
Note
Instead of MathFloor() you can use floor().
Example:
#define VALUES_TOTAL 31
//+------------------------------------------------------------------+
//| Script program start function |
//+------------------------------------------------------------------+
void OnStart()
{
//--- declare variables for conversion
double value=0; // real number for MathFloor conversion
int floor_value=0; // get the result here
//--- in a loop by the number of decimal increments of a real number
for(int i=0; i<VALUES_TOTAL; i++)
{
//--- increase the number value,
//--- get the nearest integer value from below
//--- and display control values in the journal
value+=0.1;
floor_value=(int)MathFloor(NormalizeDouble(value,1));
PrintFormat("value: %.1f, floor value: %d",value,floor_value);
