extract the number with only the first decimal number

I have to extract the number with only the first decimal number

Examples:

1.23 -> 1.2

2.49 -> 2.4

4.77 -> 4.7

7.51 -> 7.5

Extract as in? Do you want to store it in string/char/cell array of character vectors?

double!

I'd look into fix or floor.

V = [1.23, 2.49, 4.77, 7.51];

v1 = floor(V*10)/10

v1 = 1×4

1.2000 2.4000 4.7000 7.5000

v2 = fix(V*10)/10

v2 = 1×4

1.2000 2.4000 4.7000 7.5000
