* The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
+ * - arm_cortexM7lfdp_math.lib (Little endian and Double Precision Floating Point Unit on Cortex-M7)
+ * - arm_cortexM7bfdp_math.lib (Big endian and Double Precision Floating Point Unit on Cortex-M7)

+ * - arm_cortexM0l_math.lib (Little endian on Cortex-M0 / CortexM0+)
+ * - arm_cortexM0b_math.lib (Big endian on Cortex-M0 / CortexM0+)
*
* The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
- * public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
- * Define the appropriate pre processor MACRO ARM_MATH_CM4 or ARM_MATH_CM3 or
+ * public header file <code> arm_math.h</code> for Cortex-M7/M4/M3/M0/M0+ with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
+ * Define the appropriate pre processor MACRO ARM_MATH_CM7 or ARM_MATH_CM4 or ARM_MATH_CM3 or
* ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.
