*snipsnap*
The functions listed here perform operations such as rounding and
truncation of floating-point values. Some of these functions convert
floating point numbers to integer values. They are all declared in
`math.h'.
*snipsnap*
- Function: long int lrint (double X)
- Function: long int lrintf (float X)
- Function: long int lrintl (long double X)
These functions are just like `rint', but they return a `long int'
instead of a floating-point number.
*snipsnap*
bug: docu sais lrint is defined, but test shows it is not defined.
but it is implemented in libm and works correctly.
