Scientific way of expressing numbers
Very large and very small numbers are more conveniently represented in scientific notation. Scientific notation is the representation of real numbers as
a mantissa and an integer. On a computer, such an entry can be represented as MEp, where
MEp, where
M
– mantissa
E –
letter meaning 10n
p
– exponent (can be either positive or negative)
Examples
14e+6 = 14 ∙ 106 = 14 ∙ 1000000 = 14000000
16e-4 = 16 ∙ 10-4 = 16 ∙ 0.0001 = 0.0016
3.96e+3 = 3.96 ∙ 103 = 3.96 ∙ 1000 = 3960
17.356e-4 = 17.356 ∙ 10-4 = 17.356 ∙ 0.0001 = 0.0017356
0.23e+5 = 0.23 ∙ 105 = 0.23 ∙ 100000 = 23000
