Python math.ceil - Syntax
mixed ceil(mixed n);Python math.ceil library function
The math.ceil() function in Python is used to return the next highest integer value by rounding up value if necessary.
Python math.ceil - Parameter and Retun type
mixed n |
Specifies the real number (int, long, float, double) (*Required) |
|---|---|
Return int |
Returns an integer respective to an input argument. |
Example: #1 - Python math.ceil
