A.2.28 –fstore

x86:

Forces precision of floating–point expressions.

This option causes the compiler to convert the value of a floating-point expression or function to the type on the left side of an assignment rather than leave the value in a register when the following is true:

• The expression or function is assigned to a variable.

• The expression is cast to a shorter floating-point type.

To turn off this option, use the –nofstore option.

A.2.28.1 Warnings

Due to roundoffs and truncation, the results can be different from those that are generated from the register values.
