Multiple ways to parse to absolute number swift with code example

This tutorial explains how to calculate the absolute value of a number in Swift programming.

• abs() function for Int type
• fabs() function for Double type
• fabsf() function for Float type
• Int magnitude

The absolute value of a number returns a number by removing the negative sign.

For example, The input number is -123, And the absolute value is 123. If the number is 11 and the absolute value is 11.

There are multiple ways to convert to absolute value,

• One way is using the Int magnitude property and
• Another way using abs for Int, fabs for double, and fabsf for float types

Swift Convert to the absolute value

First Import the foundation into the code to use these methods

• abs() function for Int type

  It returns the absolute value of a number.

import Foundation;

var number = -123
print(abs(number)) //123
number=1231
print(abs(number)) //1231

• fabs() function for Double type

  It returns the absolute value of a number.

import Foundation;

var number:Double = -123.123
print(fabs(number)) //123.123

• fabsf() function for Float type

The fabsf() function accepts the Float type and returns absolute value.

import Foundation;

var number :Float = -123.123
print(fabsf(number))

• Use Int magnitude property of Int type

import Foundation;

var number = -345.123
print(number.magnitude) //345.123

Conclusion

There are multiple ways we can convert to absolute value for a given number. The number can be Int, Float, or Double type
