Syntax
@label@ { options } CONSTDEF [*] expression
Implemented in iMath since version 2.2.0 or earlier.
Explanation
Define a constant. The expression most be of the form symbol = expression
, and it must evaluate to a quantity.
The starred form will suppress printing of the result.
Constants are not erased by CLEAREQUATIONS
. This makes it possible to specify general constants only once in the file and reuse them for several different calculations.
Example
@c0@ CONSTDEF c_0 = 299792458 {"m" over "s"}
defines the speed of light in a vacuum.
