Syntax

PREFIXDEF { symbol = expression }

Implemented in iMath since version 2.2.0 or earlier.

Explanation

Defines a new unit prefix. The symbol is the name of the prefix, this must begin with a percent sign % to distinguish it from a variable name. The expression defines the numeric value of the prefix.

Note that a file which defines SI prefixes comes with iMath and can be activated through the References dialog.

Example

PREFIXDEF{%milli = 10^{-3} } lets iMath automatically recognize the unit %millimetre.
