Math

\[\sinh \left(x + 1\right) - \sinh x\]

↓

\[\sinh \left(x + 1\right) - \sinh x\]

C

double code(double x) {
	return ((double) (((double) sinh(((double) (x + 1.0)))) - ((double) sinh(x))));
}

↓

double code(double x) {
	return ((double) (((double) sinh(((double) (x + 1.0)))) - ((double) sinh(x))));
}

Error

Bits error versus x

Derivation

1. Initial program 0.0

   \[\sinh \left(x + 1\right) - \sinh x\]

2. Final simplification 0.0

   \[\leadsto \sinh \left(x + 1\right) - \sinh x\]
