Floating-Point Math Functions that Output Complex Results

The TI-83 Plus has two complex math modes, a + bi (rectangular coordinates) and re^ I
(polar coordinates), that allow complex numbers to be generated by functions that take
RealObj data type (floating-point) as input. If neither of these modes is set, then these
functions will generate an error when the arguments input would produce a complex
result. These functions include LnX, LogX, SqRoot, YToX and XRootY.
To have these routines return complex results for real data type inputs:
set one of the complex modes:
fmtRect, (IY + numMode)
–
– fmtPolar, (IY + numMode)
reset
fmtReal, (IY + numMode)
