/** exp10 from GNU libm fails to give precise result for integer arguments.
|
|
* For example, exp10(3) gives 1000.0000000000001
|
|
* despite the fact that 1000 is exactly representable in double and float.
|
|
* Better to always use our own implementation based on a MUSL's one.
|
|
*
|
|
* Note: the function name is different to avoid confusion with symbols from the system libm.
