The format Function in Scilab

In Scilab, the format() function plays a pivotal role in determining the display of numerical results. Consider the command:

format(n)

Here, 'n' denotes the desired number of digits to be displayed.

Moreover, this command offers the flexibility to present numbers in exponential notation, given that 'n' is a minimum of 8.

format('e', n)

For those seeking adaptability, Scilab provides an option to set an adaptive representation for numbers.

format('v', n)

In this context, while you specify the number of digits, Scilab takes the initiative to select the appropriate notation type, be it scientific, engineering, or exponential.

It's crucial to note that Scilab's format() command solely influences the display aesthetics of numbers, leaving their intrinsic value and computational precision untouched.

To illustrate, let's delve into a practical example.

Upon entering %e in the command line:

Scilab promptly displays Euler's number, the foundational base of natural logarithms.

2.7182818

To enhance the display precision to 21 digits, employ the format() command.

format(21)

Re-entering %e in the command line.

Scilab now showcases Euler's number with an extended precision of 21 digits.

2.718281828459045091

This example underscores the significance and versatility of Scilab's format() command.
