56%100

Could be two things. Here are the likely interpretations and results:

• 56% of 100: 56 (since 0.56 × 100 = 56)
• 56 mod 100 (56 % 100): 56 (remainder when 56 is divided by 100)

If you meant 56/100 as a fraction/decimal: 56/100 = 14/25 = 0.56.

Which interpretation did you have in mind? I can tailor the explanation to that.
