How to get value after decimal point in Python?

How to get value after decimal point in Python?

To get the value after the decimal point in Python, you can use the modulo operator (%) to find the remainder after dividing the number by 1. Here is an example:

“`python
num = 3.14159
decimal = num % 1
print(decimal)
“`

This will output `0.14159`, which is the value after the decimal point in the variable `num`.

How can I round the value after the decimal point in Python?

You can use the `round()` function in Python to round the value after the decimal point to a specific number of decimal places. For example, `round(decimal, 2)` will round the value to 2 decimal places.

How can I convert the value after the decimal point to an integer in Python?

You can multiply the value after the decimal point by 100 (or 1000 for 3 decimal places) and then convert it to an integer using the `int()` function. For example, `int(decimal * 100)` will convert the value to an integer.

How can I extract the integer part of a number in Python?

You can use the `int()` function to convert the floating-point number to an integer, which will automatically truncate the decimal part and return only the integer part.

How can I separate the integer and decimal parts of a number in Python?

You can use the `math.modf()` function in Python to separate the whole number and fractional part of a number. It returns a tuple with the integer and decimal parts.

How can I get the absolute value of the decimal part in Python?

You can use the `abs()` function in Python to get the absolute value of the decimal part of a number. This will remove the negative sign from the decimal part.

How can I check if a number has a decimal part in Python?

You can use the modulo operator (%) to check if a number has a decimal part. If the result of the modulo operation is not zero, then the number has a decimal part.

How can I get the number of decimal places in a float in Python?

You can convert the float to a string using the `str()` function and then count the number of characters after the decimal point to get the number of decimal places.

How can I compare the decimal part of two numbers in Python?

You can extract the decimal parts of the numbers using the modulo operator (%) and then compare them using standard comparison operators (<, >, ==, etc.).

How can I limit the decimal places in a float in Python?

You can use string formatting to limit the number of decimal places in a float. For example, `”{:.2f}”.format(num)` will limit the float to 2 decimal places.

How can I convert a string with a decimal number to a float in Python?

You can use the `float()` function in Python to convert a string with a decimal number to a float. For example, `float(“3.14”)` will convert the string “3.14” to a float.

How can I convert a float to a string with a specific number of decimal places in Python?

You can use string formatting to convert a float to a string with a specific number of decimal places. For example, `”{:.2f}”.format(num)` will convert the float `num` to a string with 2 decimal places.
