# 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
|
|||
|
|

|

{
|

|
|
//--- 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);
