Evaluate integral at specific value

I have the following mathematical function f=5sin(x), I use the int(f) to obtain the integral of my expression. Is there a way for me to evaluate the result of the integral at a specifc value, lets say 4,32,

    % define your function f, and the value a 
     syms x
a= 
f= 
I = int(f);
  subs(I,x,a)

[Ahmed Abdulla]

This substitutes x for a but doesnt evaluate the expression :(

Thank you Salah, i combined your answer with vpa to evaluate:

vpa(subs(I,x,a))

Answer 1

[Walter Roberson]

syms x
f = 5*sin(x)

f = 

fint = int(f,x,0,x)

fint = 

a = 4.32

a = 4.3200

fa = subs(fint, x, a)

fa = 

If you are expecting a decimal value, then you are wanting to get an approximation at the location, rather than the value at the location.

double(fa)

ans = 6.9120
