Swift Double isLessThanOrEqualTo()

// check if 10 is less than or equal to 10 or not
var result = 10.isLessThanOrEqualTo(10)

print(result)

// Output: true

isLessThanOrEqualTo() Syntax

The syntax of the isLessThanOrEqualTo() method is:

num.isLessThanOrEqualTo(otherNumber)

Here, num is a number.

isLessThanOrEqualTo() Parameters

The isLessThanOrEqualTo() method takes one parameter

• otherNumber - the value to test

isLessThanOrEqualTo() Return Values

The isLessThanOrEqualTo() method returns boolean value

• true - if num is less than or equal to otherNumber
• false - if num is greater than otherNumber

Example 1: Swift Double isLessThanOrEqualTo()

// check if 4 is less than or equal to 2 or not
var result1 = 4.isLessThanOrEqualTo(2)
print(result1)

// check if 2.0 is less than or equal to 2 or not
var result2 = 2.0.isLessThanOrEqualTo(2)
print(result2)

Output

false
true

Here, since 4 is not less than or equal to 2, the isLessThanOrEqualTo() method returns false. However, 2.0 is equal to 2, the method returns true.

Example 2: Using if…else With isLessThanOrEqualTo()

// check if 100 is less than or equal to 90 or not 
if 100.isLessThanOrEqualTo(90) {
  print("The condition is true")
}

else {
  print("The condition is false")
}

Output

 
The condition is false

Here, since 100 is less than or equal to 90, the condition is false so the code inside the else block is executed.
