Floating-Point Math Functions that Output Complex Results
The TI-83 Plus has two complex math modes, a + bi (rectangular coordinates) and re^θI
(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) rectangular complex
– fmtPolar, (IY + numMode) polar complex
• reset
– fmtReal, (IY + numMode) real output only
