fimf-precision, Qimf-precision

Lets you specify a level of accuracy (precision) that the compiler should use when determining which math library functions to use.

Syntax

Linux:

[

macOS:

Windows:

Arguments
value
Is one of the following values denoting the desired accuracy:
high
This is equivalent to max-error = 1.0.
medium
This is equivalent to max-error = 4; this is the default setting if the option is specified and
value
is omitted.
low
This is equivalent to accuracy-bits = 11 for single-precision functions; accuracy-bits = 26 for double-precision functions.
