Python round

round(number, ndigits) Where:

• float number is the number we want to round
• int ndigits is the offset from the decimal place

Rounding Logic

• If number ends at 0.5, it rounds to the nearest even number. example:
  • round(0.5) = 0
  • round(1.5) = 2
• If ndigits < 0, then we are going to round in the 1s, 10s, 100s, etc. example:
  • round(256.56, -2) = 300
• If ndigits = 0, or it is omited, then it returns an int

Return

Can return float if ndigits $>1$ or int if ndigits is not provided
