Mathematics with Python and Ruby/Numbers with Ruby
Ruby being weakly typed, it is only at the time of its first allocation that Ruby knows the type of a numeric variable. Ruby possesses 5 types of numeric objects:
- Integers
- Fractions (quotients of two integers)
- Real numbers (really they are decimal numbers only)
- Decimal numbers with many decimal places (Big_Num)
- and complex numbers which are not really numbers because they cannot be compared
