PCD: type conversion float32 to signed int16

I use PCD compiler v.4...

For a Project with CAN Bus I need to convert an incoming float32 number to an signed int16 number. The value of 0.1 - 200 should be converted to the value 1 - 2000 and -0.1 - -200 to -1 - -2000.

Does anybody know how this can be done in a simple way?

Or a link to help me to get further?

Many thanks for helpful ideas.

Where is the float coming from and in what form.

CCS use the microchip format for floats which is different from the IEEE standard so you may need to convert it.

Hi newguy

Thanks, amazing, it works!
A measured execution time is about 6us with
