C++ Math fmin()

The function returns the minimum value between two numbers.

Conditions:

Consider two numbers ‘x’ and ‘y’.

If(x: It returns x.
If(x>y): It returns y.
If(x=nan): It returns y.
If(y=nan):It returns x.)

Syntax

Note: If any argument has an integral type, then it is cast to double. If any other argument is long double, then it is cast to long double.

Parameter

(x,y): Values among which the minimum value is to be calculated.

Return value

It returns the minimum value between two numbers.

Example 1

Let’s see a simple example.

Output:

Values of x and y are :1.1,2.1  Minimum value is :1.1  

In this example, value of x is less than the value of y.Therefore, fmin() function returns the value of x.

Example 2

Let’s see a simple example when one of the value is nan.

Output:

Values of x and y are :10.1,nan  Minimum value is :10.1  

In this example, value of y is nan. Therefore, the value of x is returned.
