# How can I get my program to print floats?

I've written a small program to help me with my math homework:

```import math
def saCircle():
while True:
radius = float(raw_input("Enter the radius: "))
print "\nFinding area with %d as the radius" % radius
x = math.pi * radius**2
print "\nThe area of your circle is %d\n" % x
saCircle()
```

The problem is that it will accept a decimal number but it will not print out the value of the decimal number.

How can I fix this?

## Answers

Use %f instead of %d (rounds your number to an integer) to print a float:

```>>> radius = 4.4
>>> x = math.pi * radius**2
>>> print "\nThe area of your circle is %f\n" % x

The area of your circle is 60.821234
```

This question explains the difference very well.

The format specifier for floats is %f, not %d (%d is for integers).

```print "\nFinding area with %f as the radius" % radius
^
```

See the Wikipedia article on printf format strings for more details.
