The answer is that the ARM Cortex-M4F has only a *single precision* (float) FPU, and not a double precision (double) FPU. As such, it only can do float operations in hardware but not for double 32-bit Arm® Cortex®-M4, Single Precision Floating Point Unit (FPU), JTAG / SWD debug interfaces; Peripherals: 104 Configurable GPIO pins 3 UART interfaces 3 I2C interfaces 3 SPI interfaces 2 CAN 2.0B Ethernet 10/100 MAC Full-duplex SpaceWire interface DMA controller (4-Channel) 8-Ch Analog-to-digital converter (12-bit, 600ksps) The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm ® single-precision data-processing instructions and all the data types. The Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. Conceptually the Cortex-M4 is a Cortex-M3 plus DSP instructions, and optional floating-point unit (FPU). A core with an FPU is known as Cortex-M4F. Key features of the Cortex-M4 core are: ARMv7E-M architecture; 3-stage pipeline with branch speculation. Instruction sets: Thumb-1 (entire). This chapter introduces the Cortex-M4 processor and its external interfaces.

Some microcontrollers with Cortex-M4 processor do not have an FPU, so please check the datasheets carefully.
