Floating Point Numbers

Always write the entirety of floating point numbers, including the integer part.

float time = 0.5f;
double preciseTime = 0.5d;
decimal veryPreciseTime = 0.5m;

Do not start float values with a period.

// DON'T DO THIS
float time = .5f;
double preciseTime = .5d;
decimal veryPreciseTime = .5m;
