(- (tan x) (sin x))

Average Error: 10.5 → 10.5

Time: 2.3s

Precision: binary64

Math

\[\tan x - \sin x\]

↓

\[\tan x - \sin x\]

C

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

↓

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

Error

Bits error versus x

Derivation

1. Initial program 10.5

   \[\tan x - \sin x\]

2. Final simplification 10.5

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