MathCeil
MathCeil
The function returns integer numeric value closest from above.
double MathCeil(
double val // number
);Parameters
- val
[in] Numeric value.
Return Value
Numeric value representing the smallest integer that exceeds or equals to val.
Note
Instead of the MathCeil() function you can use ceil().
Example:
#define VALUES_TOTAL 31
//+------------------------------------------------------------------+
//| Script program start function |
//+------------------------------------------------------------------+
void OnStart()
{
//--- declare variables for conversion
double value=0; // real number for MathCeil conversion
int ceil_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 above
//--- and display control values in the journal
value+=0.1;
ceil_value=(int)MathCeil(NormalizeDouble(value,1));
PrintFormat("value: %.1f, ceil value: %d",value,ceil_value);
