What is the SymPy command to convert a fraction to a decimal?

To convert a fraction to a decimal in SymPy, you can use the evalf() method or the N() function.

Here's how you can do it:

1. Using evalf() method:

The evalf() method evaluates a symbolic expression to a floating-point number.

Here's an example:

from sympy import Rational
fraction = Rational(1, 3)
decimal_value = fraction.evalf()
print(decimal_value) # Output: 0.333333333333333

2. Using N() function:

The N() function is similar to evalf() and can be used to obtain a numerical approximation of a symbolic expression.

Here's an example:

from sympy import Rational, N
fraction = Rational(1, 3)
decimal_value = N(fraction)
print(decimal_value) # Output: 0.333333333333333

You can also specify the desired precision by passing an argument to evalf() or N(). For example, to get a decimal with 50 digits of precision:

from sympy import Rational, N
fraction = Rational(1, 3)
decimal_value = N(fraction, 50)
print(decimal_value)

This will give you a decimal representation with 50 digits of precision. Both methods are effective, and the choice between them often comes down to personal preference or specific use-case requirements.
