problem of conversion

[brianho]

Hi,

Below is a part of my program:

int f, location1, location2;
float ans;
float heartrate;

f = abs (location1 - location2);
heartrate = ((f*5)/1000);
ans = 1/heartrate;

There is a problem getting a correct float value of heartrate because f is an integer.
How can i get the correct float number?

Hi,

Is this MikroPascal Pro or MikroC Pro ?

Do not use "f" use something other for example "fff".


Best regards,
Peter

Hi,

it is mikcroC. it will be able to solve the problem by changing f to fff?

Hi,

The f should behave the same as fff, I have tried both variants and they worked OK.

Hi,

I tried code in MikroC Pro.

With 'f' I get "'f' Identifier redefined", if 'f' is changed to 'ff' or 'fff' or something else code is compiled.

Hello,

@tpetar
mikroC PRO for PIC will give your "...Identifier redefined", but mikroC PRO for PIC32 will not.

@brianho
Try changing your calculation like this:

Code: Select all

int f, location1, location2;
float ans;
float heartrate;

f = abs (location1 - location2);
heartrate = ((f*5.0)/1000.0); // It will tell compiler to calculate with float numbers
// if your expression contains only integers calculation will be done on integers.
ans = 1/heartrate;

Best regards.

Thank You Dejan & Filip,
