To Artifact [551406cfe8]:

• File mttroot/mtt/lib/reduce/fix_c.r — part of check-in [adc4f01f84] at 2002-05-27 10:36:21 on branch origin/master — Fix for bug [553524] #define PI causes parse error.
  Only substitutes for PI if it is not a number. This prevents Reduce from
  trying to substitute for 3.14... when "on rounded" has been set. (user: geraint@users.sourceforge.net, size: 576) [annotate] [blame] [check-ins using] [more...]

%% Fixes for c-code generation

%% Set PI explicitly here to avoid later conflict with cc headers
%% if PI is not already a number (i.e. on rounded has not been set)
LET PI = 3.1415$
IF NOT NUMBERP (pi) THEN LET PI = 3.14159$

ON ROUNDED$ % No integer output

%% Changes x^y to pow(x,y)
 OPERATOR pow$
 FOR ALL x,y LET x^y = pow(x,y)$ % Use the pow function
