Detailed Description

Each LEL function is described in this enum.

Intended use:

Internal

Review Status

Date Reviewed:
yyyy/mm/dd

Prerequisite

Etymology

This enum provides a value for each function accepted by the Lattice Expression Language classes.

Synopsis

Each function name accepted by the bridging class LatticeExprNode and passed on to the LELFunction letter classes is labelled internally with a value from this enum.

atan; atan(x) returns the arc tangent of x in the range -pi/2 to pi/2.

ATAN2 

atan2; atan2(y,x) computes an arc tangent of y/x in the range -pi to pi

EXP 

exp

LOG 

log

LOG10
