incorrect revision. the numbers are in reference to the exponent, not the coefficient.

perhaps could clarify for beginners:

// the exponent -3 divides by 1 with 3 zeroes, here with coefficient 1
1e-3 === 1 / 1000; // 0.001
// the exponent -6 divides by 1 with 6 zeroes, here with coefficient 1.23
1.23e-6 === 1.23 / 1000000; // 0.00000123

Matbe concise
// exponent -3 means dividing by 1 with 3 zeroes

@shallow-beach, @joaquinelio, thanks for your comments, I've made some changes (hope now it will be clearer for beginners). Please take a look and approve if everything's alright.
