> Hi, how does one write 10^(-8) ? > Is it as the conventional way 10**(-8) or is it 10exp(-8) ? Typing either 10**(-8) or 10^(-8) will produce a rational. Note that you don't need the parentheses and could also type 10**-8 or 10^-8. If you want a floating point number, you could type 1e-8. Checking the parents of 10^-8 and 1e-8, you will see that one lives in Rational Field (also known as QQ) and the other in Real Field with 53 bits of precision (also known as RR). sage: 10**(-8) 1/100000000 sage: 10^(-8) 1/100000000 sage: 10**-8 1/100000000 sage: 10^-8 1/100000000 sage: 1e-8 1.00000000000000e-8 sage: (10^-8).parent() Rational Field sage: (1e-8).parent() Real Field with 53 bits of precision -- You received this message because you are subscribed to the Google Groups "sage-support" group.
