SI prefixes from yocto to yotta. Precision is kept on the decimal digits you type. Everything is calculated in your browser; nothing you type is uploaded.
The number is split into its digits and power of ten without floating point, then written with one digit before the point (scientific) or an exponent that is a multiple of three (engineering).
0.000045600 is 4.5600 × 10⁻⁵, 45.600 × 10⁻⁶ in engineering notation and 45.600 µ with an SI prefix.
