Cant use float operations

Nanouser — Wed, 28 Mar 2012 18:45:24 GMT

Hi there,

i got a problem using HC12 and CW 5.9:

i want to multiply two floats:

float x = 0.1;

float y = 0.2;

float z = 0.3;

z = x *y;

if i try to run this i get following error: "L1822: Symbol _FMUL in file X:/XXXX/XXX.c.o is undefined".

operations like z = x+y; or z = x-y; are also not possible giving an according error.

why is this? how can i fix this problem? simple float multiplications should be possible!

i already removed the -D__NO_FLOAT__ parameter from the compiler settings. didn´t work. making a new project also doesn´t work, but i cant see a floating point option anywhere in the wizard anyway.

Thanks

Hello

You did not link the appropriate ANSI library file to your application.

You need to create a new project using the project wizard and make sure you enable floating point

operation in the newly created project.
