type/<=

check for a non-strict inequality

 Calling Sequence type(expr, <=)

Parameters

 expr - any expression

Description

 • The call type(expr, <=) checks if expr is of type <=, that is, if it is an inequality. It returns true if expr is of type <=, and false otherwise.
 • The type <= is a surface type check, and is therefore very fast. The supertypes relation and boolean includes this type.

 ${\mathrm{false}}$ (1)
 > $\mathrm{type}\left(a\le b,'\mathrm{<=}'\right)$
