This module comprises of truth value definitions like the whether the data is empty or blank or null or nil or its length is 0 like.

To say in one word the extended functions of value assertion functions

Summary

Functions

is_blank()

is_blank(data)

Checks for the blank Strings Spaces are treated as blank here

is_empty()

is_empty(data)

Checks the given data is empty or not . Spaces,new_lines,tabs treated as binary here

is_nan(data)

Returns true if the given data is not a number or else returns false

is_negative(num)

Checks given number is negative or not

is_none()

is_none(data)

Here except the nil and Null rest are treated as data present empty maps,tuples and lists are treated as the data

is_positive(num)

Checks given number is positive or not

is_present()

Here except the nil and Null ,data is true Even the false and true also treated as data

is_present(data)

is_zero(data)

Checks whether the passed value is zero or not
