Fix CSS log() and CSS exp() calculation

We have two simple test:

test_math_used('log(1)', '0', {type:'number'});
test_math_used('exp(0)', '1', {type:'number'});

The first test log(1) return 0. The second test exp(0) return 1.

Next, we have a calculations that sums those functions log(1) + exp(0):

test_math_used('calc(log(1) + exp(0))', '2'), {type:'number', approx:0.1};

According to the test should it should return 2, but according to the two separate tests above it should return 1.
