This template converts a decimal expression into scientific notation.

e.g. {{scinote|12345}} produces: 0×10^4

To round to a given number of significant figures, specify this number as the second unnamed parameter:

e.g. {{scinote|12345|3}} produces: 1.23×10^4

For engineering notation, set |fn=eng:

e.g. {{scinote|fn=eng|12345}} produces: 0×10^3

Trailing zeros are preserved:

e.g. {{scinote|0.001234500}} produces: 0×10^−3
