NAME

fpmath – a module for Tensile

DESCRIPTION

fpmath adds floating-point support to Tensile.

FUNCTIONS

isfloat(num)

RETURNS:true if num is a legal floating-point number

fadd(num1 num2 ...)

RETURNS:the sum of all its argument

fpostincr(var val)

adds val to var
RETURNS:old value of var

fincr(var val)

adds val to var
RETURNS:new value of var

fpostdecr(var val)

subtracts val from var
RETURNS:old value of var

fdecr(var val)

subtracts val from var
RETURNS:old value of var

fmul(val1 val2 ...)

RETURNS:a multiply of vals

fsub(val1 val2)

RETURNS:difference between val1 and val2

fdiv(val1 val2)

RETURNS:quotient of val1 and val2

fneg(val)

RETURNS:a negated val

fabs(val)

RETURNS:the absolute value of val

fint(val)

RETURNS:integral part of val

frac(val)

RETURNS:fractional part of val

fsqrt(val)

RETURNS:a square root of val

fln(val)

RETURNS:a natural logarithm of val

fsin(val)

RETURNS:a sine of val (in radians)

fcos(val)

RETURNS:a cosine of val (in radians)

fexp(val)

RETURNS:e^val

fpower(val1 val2)

RETURNS:val1^val2

fprecision([prec])

if prec is present, sets the floating point precision to it
RETURNS:the old value of precision

Comparison functions

eq, neq, less, greater, le, ge accept float as their first argument, resulting in floating point comparison
