You may be confusing Celsius and Fahrenheit. While $\displaystyle{{99}}^{\circ}\text{C}\usepackage{cmbright}\Huge\$ would be close to the boiling point of water (which is $\displaystyle{{100}}^{\circ}\text{C}\usepackage{cmbright}\Huge\$ ), $\displaystyle{{99}}^{\circ}\text{F}\usepackage{cmbright}\Huge\$ is far below the boiling point of water (which is $\displaystyle{{212}}^{\circ}\text{F}\usepackage{cmbright}\Huge\$ ).
