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
