How to find absolute value in python?

Short Tutorial: Introduction to Python

Now which function we used to identify the absolute number in python?

abs() is the function available in python to calculate the absolute number.

math.fabs() is another function available to calculate the absolute number but as a floating type.

Syntax

>>abs(value) #value is a parameter 
>>math.fabs(value) #value is a parameter

Examples of finding absolute value in python

• Absolute number of positive integer

>>abs(87)

• Absolute number of negative integer - it returns positive integer by dropping negative sign

>>abs(-67)

• Absolute value of complex number - it returns magnitude of complex number

>>abs(4+5j)

• What if calculation happens inside abs() function - it solves the equation and return positive numeral

>>abs((3*-4)+37)

• absolute value of positive floating value - it returns the same value

>>abs(3234.323)

• absolute value of negative floating value - it returns the same value by dropping the negative sign)

>>abs(-234.432)

math.fabs() examples

>>import math
>>math.fabs(68)
>>math.fabs(-987)
>>math.fabs((3*4)+37))
>>math.fabs(98.763)
>>math.fabs(-378.3232)

Note: math.fabs() not able to identify absolute value of complex number.

Conclusion

abs() and math.fabs() are two in-built python functions that we can use to calculate the absolute number.
