The math conversion API library module has the file name conv.c. This module performs math conversions. Any conversion that will uses floating-point numbers is coded to make use of the fixed-point math API.

Here is a list of functions in the math conversion API library module:

• conv_fah_2_cel
• conv_cel_2_fah

Module Dependencies

The following modules are required along with this module:

• fxp.c
• parse.c
• logger.c
• logman.c

Module Header Files

This module requires the header file:

• stdhead.h

Module Functions

conv_fah_2_cel

Prototype  : struct fxp *conv_fah_2_cel(struct fxp *s1)
Parameters :
      Name : s1
Description: input fixed-point number

Returns    : a pointer to a newly allocated fxp structure

This function will convert the input fixed-point number in degrees fahrenheit to degrees celsius. It is the responsibility of the caller to de-allocate (using fxp_free only) the new fxp structure.

conv_cel_2_fah

Prototype  : struct fxp *conv_cel_2_fah(struct fxp *s1)
Parameters :
      Name : s1
Description: input fixed-point number

Returns    : a pointer to a newly allocated fxp structure

This function will convert the input fixed-point number in degrees celsius to degrees fahrenheit. It is the responsibility of the caller to de-allocate (using fxp_free only) the new fxp structure.
