FLOAT64 Compiler Directive

Abbreviation	F64
Arguments	None.
Default	32-bit floating-point math is used.
µVision	Options — C166 — Double-precision Floating-point.
Description	The FLOAT64 directive enables 64-bit (double-precision) floating-point math for double variable types in your C programs. Variables of type float continue to use 32-bit floating-point math. By default, all floating-point math is performed using 32-bits (even when the double type is specified.) The FLOAT64 directive must be specified to use 64-bit floating-point math.
Example	C166 SAMPLE.C FLOAT64 #pragma float64
