+
+## Usage
+
+```javascript
+var incrnanprod = require( '@stdlib/stats/incr/nanprod' );
+```
+
+#### incrnanprod()
+
+Returns an accumulator `function` which incrementally computes a product, ignoring `NaN` values.
+
+```javascript
+var accumulator = incrnanprod();
+```
+
+#### accumulator( \[x] )
+
+If provided an input value `x`, the accumulator function returns an updated product. If not provided an input value `x`, the accumulator function returns the current product.
+
+```javascript
+var accumulator = incrnanprod();
+
+var prod = accumulator( 2.0 );
+// returns 2.0
+
+prod = accumulator( NaN );
+// returns 2.0
+
+prod = accumulator( 1.0 );
+// returns 2.0
+
+prod = accumulator( 3.0 );
+// returns 6.0
+
+prod = accumulator();
+// returns 6.0
+```
+
+Under certain conditions, overflow may be transient.
+
+```javascript
+// Large values:
+var x = 5.0e+300;
+var y = 1.0e+300;
+
+// Tiny value:
+var z = 2.0e-302;
+
+// Initialize an accumulator:
+var accumulator = incrnanprod();
+
+var prod = accumulator( x );
+// returns 5.0e+300
+
+// Transient overflow:
+prod = accumulator( y );
+// returns Infinity
+
+// Recover a finite result:
+prod = accumulator( z );
+// returns 1.0e+299
+```
+
+Similarly, under certain conditions, underflow may be transient.
+
+```javascript
+// Tiny values:
+var x = 4.0e-302;
+var y = 9.0e-303;
+
+// Large value:
+var z = 2.0e+300;
+
+// Initialize an accumulator:
+var accumulator = incrnanprod();
+
+var prod = accumulator( x );
+// returns 4.0e-302
+
+// Transient underflow:
+prod = accumulator( y );
+// returns 0.0
+
+// Recover a non-zero result:
+prod = accumulator( z );
+// returns 7.2e-304
+```

+
+<section class="notes">
+
+## Notes
+
+-   Input values are **not** type checked. If non-numeric inputs are possible, you are advised to type check and handle accordingly **before** passing the value to the accumulator function.
+-   For long running accumulations or accumulations of either large or small numbers, care should be taken to prevent overflow and underflow. Note, however, that overflow/underflow may be transient, as the accumulator does not use a double-precision floating-point number to store an accumulated product. Instead, the accumulator splits an accumulated product into a normalized **fraction** and **exponent** and updates each component separately. Doing so guards against a loss in precision.

+/**
+* Returns an accumulator function which incrementally computes a product, while ignoring `NaN` values.
+*
+* ## Method
+*
+* To avoid overflow/underflow, we store the fractional and exponent parts of intermediate results separately. By keeping a normalized fraction, we prevent underflow/overflow of the fraction. Underflow of the exponent is impossible, as IEEE 754 floating-point exponents are integer values. Overflow of the exponent is possible, but highly unlikely. In the worst case, an intermediate exponent is greater than the minimum safe integer, and adding the exponent of an incoming value does not change the intermediate result. While incorrect, such behavior does not lead to exponent overflow.
+*
+* While intermediate results are largely immune to overflow and not subject to underflow, this does not mean that returned results will never be zero or infinite. In fact, zero (underflow) and infinite (overflow) results may be transient (i.e., infinity followed by a finite number).
