The **`ceil()` function** returns the nearest smallest integer greater than or equal to a number. Figure 1 shows the mathematical representation of the `ceil()` function.

> The `math` module is required for this function.

# Syntax
```python
ceil(number)
```
# Parameter
This function requires a number to round up as a parameter.

# Return value
`ceil()` returns the nearest smallest integer greater than or equal to a number sent as a parameter.

# Example


import math

#positive integer sent as parameter
print "ceil(10) : ", math.ceil(10)

#negative integer sent as parameter
print "ceil(-10) : ", math.ceil(-10)

#positive float value sent as parameter
print "ceil(2.1) : ", math.ceil(2.1)

#negative float value sent as parameter
print "ceil(-2.1) : ", math.ceil(-2.1)
