Overview

In swift, the Double.greatestFiniteMagnitude property of the Double type represents the greatest finite number representable.

Syntax

Double.greatestFiniteMagnitude

Return value

This property returns the 1.7976931348623157e+308 value.

Example

Let’s look at the code below:

// get the property value
let m = Double.greatestFiniteMagnitude
// print value
print(m)
// arithmetic operations
print(m * 2) // infinity
print(m * 6 + 100) // infinity
Using the greatestFiniteMagnitude in Swift

Explanation

  • Line 2: We get the Double.greatestFiniteMagnitude property.
  • Lines 7 and 8: We perform some arithmetic operations using the property value and print the results to the console.
