`int isnan(double)` is a POSIXism 2018-06-05T06:50:20+00:00 shyouhei shyouhei@b2dd03c8-39d4-4d8f-98ff-823fe69b080e 2018-06-05T06:50:20+00:00 b5d6db65b49528c45cdfa75200dc8013d332b0db - `isnan` is something relatively new. We need to provide one for those systems without it. However: - X/Open defines `int isnan(double)`. Note the `int`. - C99 defines `isnan(x)` to be a macro. - C++11 nukes them all, undefines all the "masking macro"s, and defines its own `bool isnan(double)`. Note the `bool`. - In C++, `int isnan(double)` and `bool isnan(double)` are incompatible. - So the mess.

INFINITY is float. That of double is HUGE_VAL. 2018-01-19T01:45:36+00:00 shyouhei shyouhei@b2dd03c8-39d4-4d8f-98ff-823fe69b080e 2018-01-19T01:45:36+00:00 3ca0948f68d1055cd980992dcb68deced0f4d704 It seems HUGE_VAL is already used. Why not eliminate INTINITY. NAN is also float. That of double is called nan(). This is also fixed.
