Hello Luiz !
Thank you for the link !
But what still bugs me is the difference between heavily used
programming languages:
And after removing all modulo operations:
====
EXPR =
(((((((788)*(8.46))))+8342*1.803-1))*4186.4*(15))*(((22/((7530/((2)*(((((25))-421))))))*597)+7283.8-9.60+167))+(8871)
SQUILU = 8515287402650.3
SQLITE = 8515287402650.34
POSTGRESQL = 8515287402650.347200
D = 8.51529e+12
JAVA = 8.515287402650345E12
MYSQL = 8259816920501.086
JAVASCRIPT = 8259816920615.111
PHP = 8259816920615.1
LUA = 8259816920615.1
AMPL = 8.25982e+12
GAMS = 8.25982E+12
RUBY = 7701542593121.873
PYTHON = 7.70154259312e+12

Cheers !

Is this another instance of Rump's example?

BTW, the correct value seems to be 8.0349...E+12
