readBrukerFlexData (version 1.5)

.double2singlePrecision: Converts double to single precision.

Description

This function simulates the conversion of floating point numbers from double precision (64bit, R: double(), C: double) to single precision (32bit, R: none, C: float). It follows IEEE 754 standard.

Usage

.double2singlePrecision(x)

Arguments

x

double, numeric value which should reduce from double precision to single precision.

Value

• double (in single precision).

Details

The same could be done in C by using casts: double precision32(double value) { float x=value; return (double)x; }
