compose("%f",daily)

Ran in:
"How avoid exponential notation in compose"
Explanation: the %d conversion is for integer values. Are all of your data integer valued? (hint: no). The documentation states "If you specify a conversion that does not fit the data, such as a text conversion for a numeric value, MATLAB® overrides the specified conversion, and uses %e." By definition the %e conversion uses exponent notation.
Solution: specify a more suitable conversion, e.g. %g
daily = [-250; 156.25; -37.5];
compose("%.5g",daily)
ans = 3x1 string array
"-250" "156.25" "-37.5"
