◆ isExactlyValue() [1/2]

bool llvm::sandboxir::ConstantFP::isExactlyValue ( const APFloat & 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. The version with a double operand is retained because it's so convenient to write isExactlyValue(2.0), but please use it only for simple constants.
