1.4E-45 means

1.4*10^-45 (E stands for "exponent")

(i.e. 0.000000000000000000000000000000000000000000014)

This is the smallest possible

3.4E+38 means

3.4*10^38

(i.e. 340,000,000,000,000,000,000,000,000,000,000,000,000)

This represents the largest possible

Remember that there are also negative float numbers.
