1-3) Returns the smaller of two floating point arguments, treating NaNs as missing data (between a NaN and a numeric value, the numeric value is chosen)
4) A set of overloads or a function template for all combinations of arguments of arithmetic type not covered by 1-3). If any argument has integral type, it is cast to double. If any other argument is long double, then the return type is long double, otherwise it is double.

[edit] Parameters
x, y | - | values of floating-point or integral types |
[edit] Return value
If successful, returns the smaller of two floating point values. The value returned is exact and does not depend on any rounding modes.
[edit] Error handling
This function is not subject to any of the error conditions specified in math_errhandling
If the implementation supports IEEE floating-point arithmetic (IEC 60559),
- If one of the two arguments is NaN, the value of the other argument is returned
- Only if both arguments are NaN, NaN is returned
[edit] Notes
This function is not required to be sensitive to the sign of zero, although some implementations additionally enforce that if one argument is +0 and the other is -0, then -0 is returned.
[edit] Example
Run this code
Possible output:
fmin(2,1) = 1 fmin(-Inf,0) = -inf fmin(NaN,-1) = -1
