Compiler Warning (level 1) C4215

  • Artikkeli

nonstandard extension used : long float

The default Microsoft extensions (/Ze) treat long float as double. ANSI compatibility (/Za) does not. Use double to maintain compatibility.

The following sample generates C4215:

// C4215.cpp
// compile with: /W1 /LD
long float a;   // C4215

// use the line below to resolve the warning
// double a;
