Example A.9.2c

[nathanweeks]

I suggest the following changes to Example A.9.2c on p. 172 to avoid
compiler warnings about double-precision/single-precision conversions:

change (line 11)

Code: Select all

c[i] = (a[i] + b[i]) / 2.0;

to

Code: Select all

c[i] = (a[i] + b[i]) / 2.0f;

change (line 14)

Code: Select all

z[i] = sqrt(c[i]);

to

Code: Select all

z[i] = sqrtf(c[i]);

Thanks Nathan, that's a good suggestion.
I'll forward this to the language committee.
