Unable to perform floating point calculation

[assh_3716096]

Hi everyone !!!

I created a project and code is not being compiled due to a floating point multiplication. The line that is causing a compilation error is

lux = (1 << Exponent) * 0.01;

Without floating point multiplication, code compiles successfully.

The compilation error generated is

undefined reference to `__aeabi_d2f'

What can be done to solve this issue?

Hi,

Please have a look at  How to enable floating point operations/FPU on the CM4 of the 20719

Hi Anjana,

I'm interested in floating point calculations, however example that you pointed to shows how to print floating point numbers.

Thanks,

Hi,

Could you please confirm which chip are you using?

The chips like CYW20719 which is CM4 will support float operations.

Thanks,
Anjana
