dtvonly,

There isn't any floating-point hardware in Cortex-M3, but support for C float and double are provided in software by most compilers/libraries.

This is true for the vast majority of microcontrollers/processors currently in the market. Thank you for your help.

Hi,

Does the Cortex-M3 support the VFP as a coprocessor?

Thanks.

No, soft-float is the only option for M3.
