双精度对许多应用都不重要。

写个子程序支持吧。速度会影响一点。

话说51也是可以间接支持双精度的。。。。。。。。不过这个速度就。。。。。不眨地了。。。。

The STM32F745 line offers the performance of the Cortex-M7 core (with floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.
The STM32F746/756 lines offer the performance of the Cortex-M7 core (with floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.

The STM32F767/777 lines offer the performance of the Cortex-M7 core (with double-precision floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.

The STM32F769/779 lines offer the performance of the Cortex-M7 core (with double precision floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.
