Missing stdfloat.h common library?

Hi community.

This is my first post. I’m mainly working on ESP8266 and ESP32. For the ESP32 I’m using the esp-idf FREERTOS environment. I did already some test projects and now figured out that there is a stdint.h and a stdbool.h but no stdfloat.h which includes the float32_t. I’m wondering that this is not available, does someone have an explanation why?

Thanks and regards


PlatformIO just packages the toolchain released by Espressif. You should open an issue at, which is the build tool for the GCC based toolchain for esp8266 and esp32 chips.

As a workaround you can put the file

in the include/ folder of the project.
