# TMathBase* Define the functions Min, Max, Abs, Sign, Range for all types. NB: These functions are unfortunately not available in a portable way in std::. More functions are defined in TMath.h. TMathBase.h is designed to be a stable file and used in place of TMath.h in the ROOT miniCore. **namespace TMath** ## namespace ```cpp // Abs inline Short_t Abs(Short_t d); inline Int_t Abs(Int_t d); inline Long_t Abs(Long_t d); inline Long64_t Abs(Long64_t d); inline Float_t Abs(Float_t d); inline Double_t Abs(Double_t d); inline LongDouble_t Abs(LongDouble_t d); // Even/Odd inline Bool_t Even(Long_t a); inline Bool_t Odd(Long_t a); // SignBit template inline Bool_t SignBit(Integer a); inline Bool_t SignBit(Float_t a); inline Bool_t SignBit(Double_t a); inline Bool_t SignBit(LongDouble_t a); // Sign template inline T1 Sign( T1 a, T2 b); inline Float_t Sign(Float_t a, Float_t b); inline Double_t Sign(Double_t a, Double_t b); inline LongDouble_t Sign(LongDouble_t a, LongDouble_t b); // Min, Max of two scalars inline Short_t Min(Short_t a, Short_t b); inline UShort_t Min(UShort_t a, UShort_t b); inline Int_t Min(Int_t a, Int_t b); inline UInt_t Min(UInt_t a, UInt_t b); inline Long_t Min(Long_t a, Long_t b); inline ULong_t Min(ULong_t a, ULong_t b); inline Long64_t Min(Long64_t a, Long64_t b); inline ULong64_t Min(ULong64_t a, ULong64_t b); inline Float_t Min(Float_t a, Float_t b); inline Double_t Min(Double_t a, Double_t b); inline Short_t Max(Short_t a, Short_t b); inline UShort_t Max(UShort_t a, UShort_t b); inline Int_t Max(Int_t a, Int_t b); inline UInt_t Max(UInt_t a, UInt_t b); inline Long_t Max(Long_t a, Long_t b); inline ULong_t Max(ULong_t a, ULong_t b); inline Long64_t Max(Long64_t a, Long64_t b); inline ULong64_t Max(ULong64_t a, ULong64_t b); inline Float_t Max(Float_t a, Float_t b); inline Double_t Max(Double_t a, Double_t b); // Range inline Short_t Range(Short_t lb, Short_t ub, Short_t x); inline Int_t Range(Int_t lb, Int_t ub, Int_t x); inline Long_t Range(Long_t lb, Long_t ub, Long_t x); inline ULong_t Range(ULong_t lb, ULong_t ub, ULong_t x); inline Double_t Range(Double_t lb, Double_t ub, Double_t x); //NextPrime is used by the Core classes.
