Arithmetic Functions
********************

   This chapter contains information about functions for doing basic
arithmetic operations, such as splitting a float into its integer and
fractional parts or retrieving the imaginary part of a complex value.
These functions are declared in the header files `math.h' and
`complex.h'.

Floating Point Errors
When something goes wrong in a calculation.
Rounding
Controlling how results are rounded.
Control Functions

Arithmetic Functions
Fundamental operations provided by the library.
Complex Numbers
The types. Writing complex constants.
Operations on Complex
Projection, conjugation, decomposition.
Parsing of Numbers
Converting strings to numbers.
