On some compilers, due to historical reasons, the math library is stored separately from the rest of the standard C library. In those compilers, you must specify an additional compiler option <code>-lm</code> to link against the math library. | On some compilers, due to historical reasons, the math library is stored separately from the rest of the standard C library.
