Floating point data types.
The keyword float
usually represents a single precision floating point data type,
and double
represents a double precision floating point data type.
In TIGCC, both float
and double
(and even long double
)
are the same. The TI-89 and TI-92 Plus use a non-IEEE floating point format called SMAP II BCD
for floating point values.
These values have a range from 1e-999 to 9.999999999999999e999 in magnitude,
with a precision of exactly 16 significant digits.
Principally, the exponent range may be as high as 16383,
but a lot of math routines do not accept exponents greater than 999.
