Python’s ** format_float_scientific() function** formats a floating-point scalar as a decimal string in scientific notation.

```
format_float_scientific(x, precision=None, unique=True, exp_digits=None)
```

The `format_float_scientific()`

function takes the following parameter values:

: This represents the floating-point value to be formatted.`x`

: This represents the maximum number of digits to be printed. It takes a non-negative integer value and is optional.`precision`

: This takes boolean values (`unique`

`True`

or`False`

). If`True`

, the function uses a digit-generation strategy that gives the shortest representation. This uniquely identifies the floating-point number from other values of the same type. If`False`

, the digits are generated as if printing an infinite-precision value and stopping after precision digits. The remaining value is rounded with unbiased rounding. This is optional.: This pads the exponents with zeros until it contains at least this many digits. If omitted, the exponent will be at least`exp_digits`

`2`

digits. This is optional.

The `format_float_scientific()`

function returns the string representation of a floating point value.

from numpy import float32, format_float_scientific# creating a floating point valuex = float32(0.3)# implementing the format_float_scientific() functiony = format_float_scientific(x, precision = 10, unique = False, exp_digits = 4)print(y)print(type(y))

Implementing the format_float_scientific() function

**Line 1:**We import`float32`

and`format_float_scientific`

from the`numpy`

module.**Line 4**: We create a floating point integer of the`float32`

type using the`float32()`

function. The output value is assigned to a variable`x`

.**Line 7**: We implement the`format_float_scientific()`

function on the`x`

variable. We use a`precision`

value of`10`

, the`unique`

value as`False`

, and the`exps_digits`

value of`4`

. The output is assigned to a variable`y`

.**Line 9**: We print the variable`y`

, whose value is a string representation of the`x`

value.**Line 10**: We use the`type()`

function to check for the data type of the`y`

variable.
