(- (sin x) (tan x))

Average Error: 10.3 → 10.3

Time: 2.2s

Precision: binary64

Math

\[\sin x - \tan x\]

↓

\[\sin x - \tan x\]

C

double code(double x) {
	return ((double) (((double) sin(x)) - ((double) tan(x))));
}

↓

double code(double x) {
	return ((double) (((double) sin(x)) - ((double) tan(x))));
}

Error

Bits error versus x

Derivation

1. Initial program 10.3

   \[\sin x - \tan x\]

2. Final simplification 10.3

   \[\leadsto \sin x - \tan x\]
