Public Method ceil

static float ceil(float a)

_INSERT_METHOD_SIGNATURE_HERE_

Returns the smallest (closest to negative infinity) float value that is greater than or equal to the argument and is equal to a mathematical integer.

• If the argument value is already equal to a mathematical integer, then the result is the same as the argument.
• If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.
• If the argument value is less than zero but greater than -1.0, then the result is negative zero.

Example

   float data = Math.ceil(3.2315523f);

The example above returns a value of 4.
