Determines the smaller of the two specified values.

Syntax

double fmin(  
   double x,   
   double y  
);  
  
float fmin(  
   float x,   
   float y  
); //C++ only  
  
long double fmin(  
   long double x,   
   long double y  
); //C++ only  
  
float fminf(  
   float x,   
   float y  
);  
  
long double fminl(  
   long double x,   
   long double y  
);

Parameters

x
The first value to compare.

y
The second value to compare.

Return Value

If successful, returns the smaller of x or y.

Input	Result
`x` is NaN	`y`
`y` is NaN	`x`
`x` and `y` are NaN	nan

The function does not cause _matherr to be invoked, cause any floating-point exceptions, or change the value of errno.

Remarks

Because C++ allows overloading, you can call overloads of fmin that take and return float and long double types. In a C program, fmin always takes and returns a double.

Requirements

Routine	Required header
`fmin`, `fminf`, `fminl`	C: <math.h> C++: <math.h> or <cmath>
