Conversion Character

The conversion character specifies the notation of the output. It consists of a single
character and appears last in the format specifier.

Specifier Description

c Single character.

d Decimal notation (signed).

e Exponential notation (using a lowercase e, as in 3.1415e+00).

E Exponential notation (using an uppercase E, as in 3.1415E+00).

f Fixed-point notation.

g The more compact of %e or %f. (Insignificant zeroes do not print.)

G Same as %g, but using an uppercase E.

o Octal notation (unsigned).

s Character vector or string array.

u Decimal notation (unsigned).

x Hexadecimal notation (unsigned, using lowercase letters a–f).

X Hexadecimal notation (unsigned, using uppercase letters A–F).

For example, format the number 46 using different conversion characters to display the
number in decimal, fixed-point, exponential, and hexadecimal formats.

A = 46*ones(1,4);
txt = sprintf('%d %f %e %X', A)

txt =
'46 46.000000 4.600000e+01 2E'
