[johnmai-dev]

Swift

Python

template = env.from_string("{{ 4.5 is even }}")
result = template.render()
print(f"  4.5 is even: {result}")

template = env.from_string("{{ 4.5 is odd }}")
result = template.render()
print(f"  4.5 is odd: {result}")

template = env.from_string("{{ 3.7 is even }}")
result = template.render()
print(f"  3.7 is even: {result}")

template = env.from_string("{{ 3.7 is odd }}")
result = template.render()
print(f"  3.7 is odd: {result}")

template = env.from_string("{{ 0.1 is even }}")
result = template.render()
print(f"  0.1 is even: {result}")

template = env.from_string("{{ 0.1 is odd }}")
result = template.render()
print(f"  0.1 is odd: {result}")

4.5 is even: False
4.5 is odd: False
3.7 is even: False
3.7 is odd: False
0.1 is even: False
0.1 is odd: False
