one of a few last generation nonformula entry machines.
10+2 display, programmable and can perform numerical integration, 2d
statistics and linear regression. the keys are rubber. there are 6 `K'
memories plus the normal memory. hyperbolics are absent, so are fractions.
now why is that. the programmability is not so hot. there are 4 program slots
p1p4 designed mainly to hold formulae because conditional and
nonconditional jumps are always back to the start of the program. this
limits their usefulness. they are handy, however, to host formulae for the
builtin numerical integration.
the programming is not totally blind because the display is quite good
at showing the program function at each step. it does this on the top line
above the numbers.
although the display is better, accuracy is not better than the fx100.
it can perform trigs on values greater than 1440 degrees.
