| <h2 class="chapter">20 Arithmetic Functions</h2> |
| |
| <p>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 <samp><span class="file">math.h</span></samp> and |
| <samp><span class="file">complex.h</span></samp>. |
