◆ isExactlyValue() [1/2]

bool llvm::ConstantFPSDNode::isExactlyValue ( double V ) const

inline

We don't rely on operator== working on double values, as it returns true for things that are clearly not equal, like -0.0 and 0.0.

As such, this method can be used to do an exact bit-for-bit comparison of two floating point values. We leave the version with the double argument here because it's just so convenient to write "2.0" and the like. Without this function we'd have to duplicate its logic everywhere it's called.
