Step Four, back to the math All the calculations to date have been using 64-bit floating point math. The fractional part (the mantissa) is 52-bits. Given our largest (in magnitude) coordinate value is +-180º, that gives us an accuracy of 180 / 2^52 ~= 4 x 10-14 degrees, whic...
A binary number system is a notation in base-2. There are two bits called either 1 or 0 in the binary system. Each digit in a binary system is either 1 or 0. The bit in the binary number indicates the positional value of radix-2. A binary number syst...
A 32-bit floating-point number ranges from –3.402823e38> to +3.402823e38. The 32 bits store the sign, mantissa, and exponent of the number that yields seven digits of floating-point precision. Some numbers—for example π, 1/3, or the square root of two—can be approximated only with ...
Math formats are like rulers. The number of bits in a format’s exponent determines its range, how large an object it can measure. Its precision — how fine the lines are on the ruler — comes from the number of bits used for its mantissa, the part of a floating point number after ...
2. This term was introduced by Forsythe and Moler [1967], and has generally replaced the older term mantissa. 3 The term floating-point number will be used to mean a real number that can be exactly represented in the format under discussion. Two other parameters associated with floating-...
Thefrexpintrinsic function has been updated to return a mantissa in the range of [0.5,1.0). New intrinsic functions have been added for better debugging support. printf-- submits custom shader messages to the information queue. errorf-- submits custom shader error messages to the information qu...
So what IS volume, anyway? Simply stated, volume is a measurement of the “loudness” of a sound (to a physicist or audio engineer, the answer is MUCH more complicated than that). There are lots of ways you can calculate volume, one measurement is in decibels (dB), which is a ...
